ssh2_publickey_remove
This program uses find to locate files on a remote system and scp receive them. I used find for its many built in options.
<?php
// HOW MANY MINUTES OLD SHOULD THE FILE BE?
$file_age = 1;
// DEFINE THE LOCAL DIRECTORY (BE SURE TO USE TRAILING BACKSLASH!)
$directory_local = "/usr/home/user/";
// DEFINE THE REMOTE DIRECTORY (BE SURE TO USE TRAILING BACKSLASH!)
$directory_remote = "/usr/home/user/dropoff/";
// SSH CONNECTION INFO
$connection = ssh2_connect('ip_address/hostname', 22);
ssh2_auth_password($connection, 'user_name', 'password');
// EXECUTE THE COMMAND
$stream = ssh2_exec($connection, "find $directory_remote* -mmin +$file_age");
stream_set_blocking($stream, true);
// GET AN ARRAY OF THE OUTPUT
$arr = explode("\n", stream_get_contents($stream));
// DELETE EMPTY ELEMENTS
foreach ($arr as $value){
if ($value != ''){
$filename = str_replace($directory_remote, '', $value);
if (ssh2_scp_recv($connection, $value, $directory_local . $filename) != FALSE){
print "SCPd $value > $directory_local$filename\n";
} else {
print "Error SCPing: $value > $directory_local$filename\n";
}
}
}
fclose($stream);
?>

Trying to get a remote file with spaces in its name?
Never forget to use quotes in the remote filename, but never in the local one.
Example:
<?php
$remote_file_name="my name with spaces.ext"
ssh2_scp_recv($cn,$remote_file_name,$local_path."/".$remote_file_name); // ERROR
ssh2_scp_recv($cn,"\"".$remote_file_name."\"",$local_path."/".$remote_file_name); //OK
ssh2_scp_recv($cn,"\"".$remote_file_name."\"","\"".$local_path."/".$remote_file_name."\""); //ERROR
?>
So, the quotes in the file name are needed only for remote, not for local.

This function can be used to copy all files into a directory on a remote server, using SSH and SCP.
<?php
$connection = ssh2_connect('host', 22);
ssh2_auth_password($connection, 'user', 'password');
$remote_dir="/remote_dir/";
$local_dir="/local_dir/";
$com ="ls $remote_dir";
$stream = ssh2_exec($connection, $com);
stream_set_blocking($stream,true);
$cmd=fread($stream,4096);
$arr=explode("\n",$cmd);
$total_files=sizeof($arr);
for($i=0;$i<$total_files;$i++){
$file_name=trim($arr[$i]);
if($file_name!=''){
$remote_file=$remote_dir.$file_name;
$local_file=$local_dir.$file_name;
if(ssh2_scp_recv($connection, $remote_file,$local_file)){
echo "File ".$file_name." was copied to $local_dir<br />";
}
}
}
fclose($stream);
?>

Being still in Beta, I guess it will have it quirks. One I found was that if the remote filename has brackets in it, it just wont work.
I should file it as a bug report, but find the process all intimidating really - I am always just a stupid user who does not know what he is on about!
But anyway - the work around of renaming the file before downloading it works fine.
use:
$_new_path = str_replace("(", "", $_path );
$_new_path = str_replace(")", "", $_new_path );
ssh2_sftp_rename( $sftp, $_path, $_new_path );
To tell you the truth I haven't determined if it is the open or close bracket, or both. Someone else can investigate that.
Meanwhile, it would be good to know all the bad filename characters which this function has problems with, no doubt there are more.

Problem:
can't pass an array to sftp_scp_rec()
also: for Windows: sftp was not happy when connecting to a Windows dir.
eg: sftp_scp_rec($connection, "remote/directory","local/$directory[$i]");
Solution:
The array was placing whitespace on the end of the variable.
trim(" ","",$directory[$i]);
connecting to Windows dir:
sftp_scp_rec($connection, "linux/directory","\\windows\share[$i]");
This script backs up remote Linux directories to a local Windows directory based on modified dates of files.
The Idea is to get a complete back up of a directory via ftp client etc.
Then when the script runs it will back up newly modified files only.

If when trying to use this function you get "Warning: ssh2_scp_send(): Failure creating remote file," then try using
$data = file_get_contents("ssh2.sftp://$sftp/path/to/file");

If you scan a remote directory for a list of files by using opendir and readdir on a path obtained from ssh2_sftp(), you'll end up with a list of full file paths containing the ssh2.sftp://$sftp prefix, where $sftp is the sftp resource string returned by ssh2_sftp.
If you later attempt to use ssh2_scp_recv() (even on the same connection!) to copy files locally from the remote path, the copy operation will fail because ssh2_scp_recv() doesn't like the wrapper path prefix. It expects remote file references to be rooted at the base of the remote file system (eg., '/').
Moral: ssh2_scp_recv() likes paths rooted at the file system root on the remote machine, not full network paths. This routine will fail with an obscure message about not being able to copy the files - yet when you go look it works fine. Worse, when you connect and copy them from an scp shell session, it also works fine.
