mb_eregi_replace — Replace regular expression with multibyte support ignoring case
Scans string for matches to pattern , then replaces the matched text with replacement .
The regular expression pattern. Multibyte characters may be used. The case will be ignored.
The replacement text.
The searched string.
The resultant string or FALSE on error.
Note: The internal encoding or the character encoding specified by mb_regex_encoding() will be used as the character encoding for this function.
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.
