mb_eregi_replace

(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

mb_eregi_replaceReplace regular expression with multibyte support ignoring case

Description

mb_eregi_replace(
    string $pattern,
    string $replacement,
    string $string,
    ?string $options = null
): string|false|null

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.

replacement

The replacement text.

string

The searched string.

options
The search option. See mb_regex_set_options() for explanation.

Return Values

The resultant string or false on error. If string is not valid for the current encoding, null is returned.

Changelog

Version Description
8.0.0 options is nullable now.
7.1.0 The function checks whether string is valid for the current encoding.
7.1.0 The e modifier has been deprecated.

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.

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
