mb_ereg
when trying to find a way to strip newline from a multibyte UTF-8 string i got to this function just to discover later that POSIX don't "do" newline so i can't strip them, examples of what i tried are : \r\n , \\r\\n , (\\r\\n) (\\r|\\n)
and got no result
so since i wanted something like mb_nl2br() that's simple i wrote this little recursive function for UTF-8:
<?php
function mb_str_replace($find,$replace,&$str)
{
$i = mb_strpos($str,$find, 0,"UTF-8");
if ($index===false) {return;}
$str = mb_substr($str, 0,$i).$replace.mb_substr($str, $i+mb_strlen($find,"UTF-8"),mb_strlen($str,"UTF-8"));
$this->mb_str_replace($find,$replace,$str);
}
?>
note: moderate unit tesing was done, changed to other encodings
mb_eregi_replace
(PHP 4 >= 4.2.0, PHP 5)
mb_eregi_replace — Replace regular expression with multibyte support ignoring case
Description
string mb_eregi_replace
( string
$pattern
, string $replace
, string $string
[, string $option = "msri"
] )
Scans string for matches to
pattern, then replaces the matched text
with replacement.
Parameters
-
pattern -
The regular expression pattern. Multibyte characters may be used. The case will be ignored.
-
replace -
The replacement text.
-
string -
The searched string.
-
option -
optionhas the same meaning as in mb_ereg_replace().
Return Values
The resultant string or FALSE on error.
Notes
Note:
The internal encoding or the character encoding specified by mb_regex_encoding() will be used as the character encoding for this function.
Warning
Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace()). Not taking care of this will most likely create remote code execution vulnerabilities in your application.
