XII. CURL, Client URL Library Functions

소개

PHP supports libcurl, a library created by Daniel Stenberg, that allows you to connect and communicate to many different types of servers with many different types of protocols. libcurl currently supports the http, https, ftp, gopher, telnet, dict, file, and ldap protocols. libcurl also supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading (this can also be done with PHP's ftp extension), HTTP form based upload, proxies, cookies, and user+password authentication.

These functions have been added in PHP 4.0.2.

요구 사항

In order to use the CURL functions you need to install the CURL package. PHP requires that you use CURL 7.0.2-beta or higher. PHP will not work with any version of CURL below version 7.0.2-beta. In PHP 4.2.3, you will need CURL version 7.9.0 or higher. From PHP 4.3.0, you will need a CURL version that's 7.9.8 or higher. PHP 5.0.0 will most likely require a CURL version greater than 7.10.5

설치

To use PHP's CURL support you must also compile PHP --with-curl[=DIR] where DIR is the location of the directory containing the lib and include directories. In the "include" directory there should be a folder named "curl" which should contain the easy.h and curl.h files. There should be a file named libcurl.a located in the "lib" directory. Beginning with PHP 4.3.0 you can configure PHP to use CURL for URL streams --with-curlwrappers.

Note to Win32 Users: In order to enable this module on a Windows environment, you must copy libeay32.dll and ssleay32.dll from the DLL folder of the PHP/Win32 binary package to the SYSTEM folder of your Windows machine. (Ex: C:\WINNT\SYSTEM32 or C:\WINDOWS\SYSTEM)

예제

Once you've compiled PHP with CURL support, you can begin using the CURL functions. The basic idea behind the CURL functions is that you initialize a CURL session using the curl_init(), then you can set all your options for the transfer via the curl_setopt(), then you can execute the session with the curl_exec() and then you finish off your session using the curl_close(). Here is an example that uses the CURL functions to fetch the example.com homepage into a file:

예 1. Using PHP's CURL module to fetch the example.com homepage

<?php

$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);
curl_close($ch);
fclose($fp);
?>

차례
curl_close -- Close a CURL session
curl_copy_handle --  Copy a cURL handle along with all of it's preferences
curl_errno -- Return the last error number
curl_error --  Return a string containing the last error for the current session
curl_exec -- Perform a CURL session
curl_getinfo --  Get information regarding a specific transfer
curl_init -- Initialize a CURL session
curl_multi_add_handle --  Add a normal cURL handle to a cURL multi handle
curl_multi_close --  Close a set of cURL handles
curl_multi_exec --  Run the sub-connections of the current cURL handle
curl_multi_getcontent --  Return the content of a cURL handle if CURLOPT_RETURNTRANSFER is set
curl_multi_info_read --  Get information about the current transfers
curl_multi_init --  Returns a new cURL multi handle
curl_multi_remove_handle --  Remove a multi handle from a set of cURL handles
curl_multi_select --  Get all the sockets associated with the cURL extension, which can then be "selected"
curl_setopt -- Set an option for a CURL transfer
curl_version -- Return the current CURL version

For anyone who is having trouble getting some of the advanced functionality to work in whatever version of PHP you have, I wrote a little wrapper for the command line version of curl. The function below is for Windows (hence, the curl.exe), but it works the same way under Linux or whatever.

The curl man page enumerates a ton of options you can use...

function curlPageGrabber($destinationURL, $refererURL, $postData, $autoForward = false, $autoGrabCookies = true, $curlDebug = false)
  {
  $curlString = "c:\curl\curl.exe -i -v -m 30 -L -b c:\curl\cookiejar.txt -c c:\curl\cookiejar.txt ";
  $curlString .= " -A \"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322;)\" ";
  $curlString .= " -H \"Accept-Language: en-us\" ";
  $curlString .= " -H \"Accept-Encoding: gzip, deflate\" ";
  $curlString .= " -H \"Host: affiliate-program.amazon.com\" ";
  $curlString .= " -H \"Accept: */*\" ";
  $curlString .= " --compressed ";
  //$curlString .= " --trace-ascii ";
 
  if ($refererURL != '')
   {
   $curlString .= "-e \"".$refererURL."\" ";
   }
  if ($postData != '')
   {
   $curlString.= " -d \"$postData\" ";
   }
  $curlString .= $destinationURL;
  if ($curlDebug == true)
   {
   echo "<p>curlString: $curlString</p>";
   }
 
  $temp = exec($curlString, $retval);

  $htmlData = '';
  foreach ($retval as $arrayLine)
   {
   $htmlData .= $arrayLine."\r\n";
   }
  if ($curlDebug == true)
   {
   echo "<textarea cols=80 rows=20>$htmlData</textarea>";
   }
 
  return $htmlData;
 
 
  } // end function

Note that on Win32 this documentation can get a little confusing.

In order to get this to work you need to:

1) Be sure that the folder where libeay32.dll and ssleay32.dll - tipically C:\\PHP - is present on the PATH variable.

2) Uncomment - remove the semi-colon - the line that says "extension=php_curl.dll" from php.ini

3) Restart the webserver (you should already know this one, but...)

It took me some time to realize this, since this page doesn't mention the need to uncomment that php.ini's line.

This may be obvious to everybody *except* me, but if you want to use curl to connect via ftp rather than http, then you just need to use "ftp://" in the url specification (I was looking for an use_ftp flag or something). 

Use the CURLOPT_USERPWD to login to the ftp site.

/*
Sean Huber CURL library

This library is a basic implementation of CURL capabilities.
It works in most modern versions of IE and FF.

==================================== USAGE ====================================
It exports the CURL object globally, so set a callback with setCallback($func).
(Use setCallback(array('class_name', 'func_name')) to set a callback as a func
that lies within a different class)
Then use one of the CURL request methods:

get($url);
post($url, $vars); vars is a urlencoded string in query string format.

Your callback function will then be called with 1 argument, the response text.
If a callback is not defined, your request will return the response text.
*/

class CURL {
   var $callback = false;

function setCallback($func_name) {
   $this->callback = $func_name;
}

function doRequest($method, $url, $vars) {
   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, $url);
   curl_setopt($ch, CURLOPT_HEADER, 1);
   curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);

When you try to login to a page using cURL, you could experience problems when you're not providing the right URL.

For instance, if you use the front page to login (http://awebsite.com/) where to form is located, you will receive a http 405 error, instead view the source and see what the form's action is, it might just be: http://awebsite.com/processlogin.php

Took me hours to find this out, hope it can save someone else's time.

Beware of any extra spaces in the URL.  A trailing space in the URL caused my script to fail with the message "empty reply from server".

The examples below for HTTP file upload work great, but I wanted to be able to post multiple files through HTTP upload using HTML arrays as specified in example 38.3 at

http://us3.php.net/features.file-upload

In this case, you need to set the arrays AND keys in the $post_data, it will not work with just the array names. The following example shows how this works:

<?php

   $post_data = array();
  
   $post_data['pictures[0]'] = "@cat.jpg";
   $post_data['pictures[1]'] = "@dog.jpg";
  

   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, "http://my.domain.com/my_url.php" );
   curl_setopt($ch, CURLOPT_POST, 1 );
   curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   $postResult = curl_exec($ch);

   if (curl_errno($ch)) {
       print curl_error($ch);
   }
   curl_close($ch);
   print "$postResult";

I had the following experience when harvesting urls with a get variable from a page using cUrl. HTML pages will output ampersands as &amp when the page is read by the curl function.

If you code a script to find all hyperlinks, it will use &amp instead of &, especially using a regular expression search.

It is hard to detect because when you output the url to the browser it renders the html. To fix, add a line to replace the &amp with &.

function processURL($url){
       $url=str_replace('&amp;','&',$url);
       $ch=curl_init();
       curl_setopt($ch, CURLOPT_URL, $url);
       curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
       $xml = curl_exec ($ch);
       curl_close ($ch);
       echo $xml;
   }
}

To shed some light on some of the numbers trucex at gmail has in his tests, some of the web pages (Yahoo and GoDaddy) downloaded at exceptionally faster speeds than with file_get_contents().  This is simply because CURL accepts (by default) compression protocols such as deflate and gzip.

Most likely GoDaddy.com may be using compression for specific HTTP clients including CURL.  I know for a fact that Yahoo.com and Google.com use gzip compression.  You can test servers for gzip compression here:  http://www.whatsmyip.org/mod_gzip_test/

For the sake of performance, I would recommend the use of CURL.  if performance was not an issue and I wanted to keep my code simple and portable (for PHP servers without the cURL extension) I would use file_get_contents().

If you're getting trouble with cookie handling in curl:

- curl manages tranparently cookies in a single curl session
- the option
curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookieFileName");

makes curl to store the cookies in a file at the and of the curl session

- the option
curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp/cookieFileName");

makes curl to use the given file as source for the cookies to send to the server.

so to handle correctly cookies between different curl session, the you have to do something like this:

       $ch = curl_init();
       curl_setopt ($ch, CURLOPT_URL, $url);
       curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE_PATH);
       curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE_PATH);

       curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
       $result = curl_exec ($ch);
       curl_close($ch);
       return $result;

in particular this is NECESSARY if you are using PEAR_SOAP libraries to build a webservice client over https and the remote server need to establish a session cookie. in fact each soap message is sent using a different curl session!!

I hope this can help someone

In replay to trucexs post,

You are right in case if we will talk about simple script, like you mention. Now just imagine situation when you will need to create some kind of web based proxy (example gesoft.org)? Can it be done by using simple functions like file_get_contents? The answer will be positive, but at the same time dont forget the time which will be spend to do the same job. Is it worth to spend more time?

Now most important thing in which I will never agree, is it possible to execute more than 1000 threads at the same? Yes and here is an example of it. proxy-list.org. 1000 proxies are rechecked every 10 min. The difference between first proxy testing and last one could be easily calculated and it will be equal something about 46 seconds. It should be mentioned that this testing script not only executed and stopped but it has 30 seconds timeout!!! That means that script can not finish its work 30 seconds earlier.

According my stats, if just simple web page will be opened by curl, there is possibility to execute up to 10k threads at the same time.

One more important parameter is which amount of possible simultaneously threads can be executed depends directly proportionally on hosting quality! Such as, busyness, CPU, RAM, at list internet channel quality and speed.

Regards and good luck in you work

I've seen a few people claim things like curl executing 2000 requests per minute (I didn't believe it, but see godaddy.com in the results below). I've also gotten into 5-6 arguments about the speed of cURL vs. other alternatives.

To stop the argument once and for all, I've created a script that will test cURL retreiving a page 50 times and file_get_contents 50 times, on a variety of different URL's.

For simplicity, I have only retreived the page from the remote site and then went on to the next request. All URL's are using the HTTP protocal; FTP is not tested.

Here are the results of the script on one execution:

Calculating 50 queries to http://www.flickr.com/.
cURL took 9.550734 seconds.
file_get_contents() took 10.878360 seconds.

Calculating 50 queries to http://www.yahoo.com/.
cURL took 4.729566 seconds.
file_get_contents() took 10.443786 seconds.

Calculating 50 queries to http://www.ebay.com/.
cURL took 46.348250 seconds.
file_get_contents() took 52.685604 seconds.

Calculating 50 queries to http://www.godaddy.com/.
cURL took 1.505460 seconds.
file_get_contents() took 37.154304 seconds.

Calculating 50 queries to http://www.php.net/.
cURL took 13.136836 seconds.
file_get_contents() took 17.981879 seconds.

You may test this yourself while the script is up as well. Make a note that the page will take a few minutes to load completely (add all of the result times above and then some).

Hello everybody,
The solution how to use proxy in correct way with curl was founded. Here is the part of code which was successfully used for checking proxy server and can be used by anybody as an example. During the research one very useful parameter of curl was discovered: CURLOPT_TIMEOUT. If script is using curl object with proxy parameter it is very important to set this parameter. There is possibility that proxy will not replay (die or big latency) until PHP scripts timeout exceed.

   $cUrl = curl_init();
   curl_setopt($cUrl, CURLOPT_URL, $requestUrl);
   curl_setopt($cUrl, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($cUrl, CURLOPT_TIMEOUT, 'timeout_in_seconds');
   curl_setopt($cUrl, CURLOPT_PROXY, 'proxy_ip:proxy_port');
   $pageContent = trim(curl_exec($cUrl));
   curl_close($cUrl);

Hope this post will be useful
Sincerely yours
Vitali Simsive
P.S. The example of working script can be seen here http://proxy-list.org/admin/checkproxy.php?proxy=ip:port&timeout=sec
If somebody is interesting to obtain personal copy of checkproxy.php please mail me.

To setup http proxy for connection use CURLPROXY_HTTP.

I found it is something problematic to configure connection based on CURLOPT_PROXY.

curl_setopt ( resource ch, CURLPROXY_HTTP, 'http://host:port');

To use proxy in cUrl, not only CURLOPT_PROXY parameter should be set but CURLOPT_HTTPPROXYTUNNEL (to 1 or true) and CURLOPT_PROXYUSERPWD (if proxy requires authorization) as it was written in the cUrls official documentation.
Working code should be something like this:

$cUrl = curl_init();
curl_setopt($cUrl, CURLOPT_URL, google.com);
curl_setopt($cUrl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($cUrl, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($this->cUrl, CURLOPT_PROXY, 'proxy_name_or_ip:proxy_prot');
curl_setopt($this->cUrl, CURLOPT_PROXYUSERPWD, 'username:password');
$PageContent = curl_exec($cUrl);
curl_close($cUrl);

To be honest this code does not work on my server. Parameters different variation had tried but in vain, the code still did not work. Finally personal proxy server was bought and checking started again, the result was negative again.

Before bringing up this question here, it was asked on many different PHP forums but in vain, nobody had the answer. There is only one suspicion: there is possibility that there is something wrong with hosting where this code was tested.

To find the right answer the code should be tested in different hosting.

TIP: If you are using fopen and fread to read HTTP or FTP or Remote Files, and experiencing some performance issues such as stalling, slowing down and otherwise, then it's time you learned a thing called cURL.

Performance Comparison:

10 per minute for fopen/fread for 100 HTTP files
2000 per minute for cURL for 2000 HTTP files

cURL should be used for opening HTTP and FTP files, it is EXTREMELY reliable, even when it comes to performance.

I noticed when using too many scripts at the same time to download the data from the site I was harvesting from, fopen and fread would go into deadlock. When using cURL i can open 50 windows, running 10 URL's from each window, and getting the best performance possible.

Just a Tip :)

Also here is some quick code that I use in my scripts now, of course credits go to other PHP'ers who have posted on this page, so I take zero credit.

TO POST TO A PAGE USING values and fields:
<?
$url="http://anything";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, "fieldname=fieldvalue&fieldname=fieldvalue&");
#curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$store = curl_exec ($ch);
$content = curl_exec ($ch); # This returns HTML
curl_close ($ch);
?>

TO GET A PAGE USING A URL ONLY:
<?
$url="http://anything";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$store = curl_exec ($ch);
$xml = curl_exec ($ch);
curl_close ($ch);

Just an addition to ksavage's script. Iam using HSBC API method of integration.

We may not need those array of xml tags.
We may need to check and fetch values of few strings.

<?

print_r($vals);  // print all the arrays.

print_r($vals[29]); // print only the selected array.

//prints something like below.

//Array ( [tag] => ProcReturnMsg [type] => complete [level] => 6 [attributes] => Array ( [DataType] => String ) [value] => Approved )

$val1 = $vals[29];

print_r ($val1[tag]);  // ProcReturnMsg

print_r ($val1[value]); //Approved

Hello!

CURL function make security hole at your site....

Just read that PHP cURL functions bypass open_basedir

protection, so users can navigate through

filesystem.
For example, setting "open_basedir" in php.ini to

"/var/www/html" anybody can retrieve "/etc/parla"

using cURL functions.

== Proof of concept (curl.php)

<?php

$ch = curl_init("file:///etc/parla");

$file=curl_exec($ch);

echo $file

?>

After trying both ksavage and mmm's attempts to send HTTP POST's with full xml in them, I was finally successful after using an obscure content-type (multipart/mixed) with a boundary declaration. Incidentally, CURLOPT_CUSTOMREQUEST only accepts method names like 'POST' or 'PUT', not entire headers. You need to use CURLOPT_HTTPHEADER.

<?php
$request = "<xml>...</xml>";

       $header[] = "Host: $host";
       $header[] = "MIME-Version: 1.0";
       $header[] = "Content-type: multipart/mixed; boundary=----doc";
       $header[] = "Accept: text/xml";
       $header[] = "Content-length: ".strlen($request);
       $header[] = "Cache-Control: no-cache";
       $header[] = "Connection: close \r\n";
       $header[] = $request;
    
       $ch = curl_init();
       curl_setopt($ch, CURLOPT_URL,$url);
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
       curl_setopt($ch, CURLOPT_TIMEOUT, 4);
       curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'POST');
       curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
?>

On the other side, the server grabs the post data and strips the boundaries.

<?php
         $somecontent = $HTTP_RAW_POST_DATA;
         $somecontent = trim(str_replace('----doc','',$somecontent));
        
         echo $somecontent;
         //returns <xml>...</xml>
?>

Back at the client, the server's output is taken by curl_exec() and stored in $data

<?php
  $data = curl_exec($ch);       
       if (curl_errno($ch)) {
           print curl_error($ch);
       } else {
           curl_close($ch);
           echo $data;
           //returns <xml>...</xml>
       }
?>

Compared to SOAP or REST, this is really an enormous pain, plus the server still has to parse the xml to be able to use it. But sometimes it's unavoidable. Enjoy.

Problems can occur if you mix CURLOPT_URL with a 'Host:' header in CURLOPT_HEADERS on redirects because cURL will combine the host you explicitly stated in the 'Host:' header with the host from the Location: header of the redirect response.

In short, don't do this:

$host = "www.dontusehostheaders.com";
$url = "http://$host/";

$headers = array("Host: $host");

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

Do this instead:

$host = "www.dontusehostheaders.com";
$url = "http://$host/";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

About CURLOPT_ENCODING:
added in curl in 7.10 - Oct 1 2002
In 7.10.5 - May 19 2003 syntax was chnaged:

Had one heck of a time getting curl to send my XML request.  Tried a lot of different things, FINALLY ended up with this. 

Im making a curl request to paymentech / Orbital 's payment gateway.  Essentially, I took the same header i made for the fsockopen() request, and used it for this curl request. (Hostinc company didnt allow fsockopen().

You'll note that this specific gateway requires a custom content type header.  Thats what gave me the most trouble.  When using the CURLOPT_HTTPHEADER, and CURLOPT_POSTFIELDS together, it doesnt matter, it sends the default post header because of CURLOPT_POSTFIELDS.

<?php

$url = "https://your.gateway.url";
$page = "/proccessing_page.cgi";

$post_string = "<YourXML>All XML stuff Here</YourXML>";

       $header  = "POST ".$page." HTTP/1.0 \r\n";
       $header .= "MIME-Version: 1.0 \r\n";
       $header .= "Content-type: application/PTI26 \r\n";
       $header .= "Content-length: ".strlen($post_string)." \r\n";
       $header .= "Content-transfer-encoding: text \r\n";
       $header .= "Request-number: 1 \r\n";
       $header .= "Document-type: Request \r\n";
       $header .= "Interface-Version: Test 1.4 \r\n";
       $header .= "Connection: close \r\n\r\n";
       $header .= $post_string;
      
       $ch = curl_init();
       curl_setopt($ch, CURLOPT_URL,$url);
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
       curl_setopt($ch, CURLOPT_TIMEOUT, 4);
       curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);

       $data = curl_exec($ch);        if (curl_errno($ch)) {
           print curl_error($ch);
       } else {
           curl_close($ch);
       }

// use XML Parser on $data, and your set!

       $xml_parser = xml_parser_create();
       xml_parser_set_option($xml_parser,XML_OPTION_CASE_FOLDING,0);
       xml_parser_set_option($xml_parser,XML_OPTION_SKIP_WHITE,1);
       xml_parse_into_struct($xml_parser, $data, $vals, $index);
       xml_parser_free($xml_parser);

// $vals = array of XML tags.  Go get em!

?>

Worked like a dream for me.  Enjoy!

Here's a function that I needed and couldn't use CURL... it helps you if you want to send the POST data (instead of GET) from one form to 2 or more other PHP scripts.  Trust me... it's a life saver!!

     function HTTP_Post($URL,$data, $referrer="") {

       // parsing the given URL
       $URL_Info=parse_url($URL);

       // Building referrer
       if($referrer=="") // if not given use this script as referrer
         $referrer=$_SERVER["SCRIPT_URI"];

       // making string from $data
       foreach($data as $key=>$value)
         $values[]="$key=".urlencode($value);
       $data_string=implode("&",$values);

       // Find out which port is needed - if not given use standard (=80)
       if(!isset($URL_Info["port"]))
         $URL_Info["port"]=80;

       // building POST-request:
       $request.="POST ".$URL_Info["path"]." HTTP/1.1\n";
       $request.="Host: ".$URL_Info["host"]."\n";
       $request.="Referer: $referer\n";
       $request.="Content-type: application/x-www-form-urlencoded\n";
       $request.="Content-length: ".strlen($data_string)."\n";
       $request.="Connection: close\n";
       $request.="\n";
       $request.=$data_string."\n";

       $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
       fputs($fp, $request);
       while(!feof($fp)) {
           $result .= fgets($fp, 128);
       }
       fclose($fp);

       return $result;
     }

     $output1=HTTP_Post("http://www.server1.com/script1.php",$_POST);
     $output2=HTTP_Post("http://www.server2.com/script2.php",$_POST);

If you're trying to post forms to an ASP.NET server, you will need to include the value of the __VIEWSTATE hidden field in your post. You can get it like this:

$html = curl_exec($ch);
$matches = array();
preg_match('/<input type="hidden" name="__VIEWSTATE" value="([^"]*?)" \/>/', $html, $matches);
$viewstate = $matches[1];
$viewstate = urlencode($viewstate);

That last urlencode() is the bit that drove me crazy for a while.

btw, CURLOPT_HTTPHEADER expects an array:

$myHeader = array(
   "MIME-Version: 1.0",
   "Content-type: text/html; charset=iso-8859-1",
   "Content-transfer-encoding: text",
);
  
curl_setopt($ch, CURLOPT_HTTPHEADER, $myHeader);

(hope this saves someone several hours of...)

A note of warning for PHP 5 users: if you try to fetch the CURLINFO_CONTENT_TYPE using curl_getinfo when there is a connect error, you will core dump PHP. I have informed the Curl team about this, so it will hopefully be fixed soon. Just make sure you check for an error before you look for this data.

In recent versions of php, CURLOPT_MUTE has (probably) been deprecated. Any attempt of using curl_setopt() to set CURLOPT_MUTE will give you a warning like this:

PHP Notice:  Use of undefined constant CURLOPT_MUTE - assumed 'CURLOPT_MUTE' in ....

If you wish tu silence the curl output, use the following instead:

   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

And then,

   $curl_output=curl_exec($ch);

The output of the curl operation will be stored as a string in $curl_output while the operation remains totally silent.

Multipart form uploads (ie simulating the upload of files from a browser form) is surprisingly easy, yet hard to find information on.... hope this changes that.

$postData = array();

//simulates <input type="file" name="file_name">
$postData[ 'file_name' ] = "@test.txt";
$postData[ 'submit' ] = "UPLOAD";
      
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url );       
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POST, 1 );

//seems no need to tell it enctype='multipart/data' it already knows
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData );

$response = curl_exec( $ch );

//where test.txt is a file in the same directory!

If you have upgraded to using thread safe PHP (with apache 2 MPM=worker) note that
CURLOPT_COOKIEJAR / CURLOPT_COOKIEFILE both need an absolute path set for the cookie file location and no longer take a relative path.
(As before, also remember to have set correct permissions to allow a writeable cookie file/dir by apache)

It took me quite some to to figure out how to get Curl (with SSL), OpenSSL and PHP to play nicely together.

After reinstalling MS-VC7 and compiling OpenSSL to finally realise this was'nt nesscary.

If your like me and like *Nix systems more than Windows then you'll most probly have similar problems.

I came across this, on a simple google with the right keywords.

http://www.tonyspencer.com/journal/00000037.htm

I read thru that and found my mistake.

Its just a small list of notes, I found them to be the best I've found on the subject and the most simplist.

Dont forget to add a simple line like this into your scripts to get them working on Win32.

<?php
if($WINDIR) curl_setopt($curl, CURLOPT_CAINFO, "c:\\windows\\ca-bundle.crt");
?>

Last note: ca-bundle.crt file is located in the Curl download. I stored mine in the windows directory and apache/php can access it fine.

All the best and I hope this helps.

You can request (and have deflated for you) compressed http (from mod_gzip or ob_gzhandler, for instance) by using the following:

curl_setopt($ch,CURLOPT_ENCODING , "gzip");

This seems to work fine with the latest php (4.3.4) curl (7.11.0) and zlib (1.1.4) under linux.  This is much more elegant than forcing the Accept-Encode header and using gzdeflate on an edited result.

I know that many people suffer from cURL when trying to send XML data. I solved this problem and want to share it with you:

I was trying to send SMS messages with a SMS service provider. They gave me the following ASP code, where you send data as XML and receive a response in XML as well:

url = "http://...someaddress/somefile.asp";
xmldata ="<XMLtag1>many other tags, data here</XMLtag1>";
Set ob = Server.CreateObject("Msxml2.XMLHTTP")
ob.Open "POST",url,false
ob.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
ob.Send xmldata
...then recieve code was here...

This is done in PHP using cURL library in this way:

<?php
$XPost = "<XMLcontent>sameas above</XMLcontent>"
$url = "..same URL as above..";
$ch = curl_init();    // initialize curl handle
curl_setopt($ch, CURLOPT_URL,$url); // set url to post to
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
curl_setopt($ch, CURLOPT_TIMEOUT, 4); // times out after 4s
curl_setopt($ch, CURLOPT_POSTFIELDS, $XPost); // add POST fields
$result = curl_exec($ch); // run the whole process
echo $result; //contains response from server
?>

Some say that you should use CURLOPT_CUSTOMREQUEST, CURLOPT_HTTPHEADER and etc. to perform this task , as you can see you don't need those at all.

Hope it will help those who tries to simulate Msxml2.XMLHTTP or simply try sending XML data over PHP.
