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.



The regular expression pattern. Multibyte characters may be used. The case will be ignored.


The replacement text.


The searched string.

option has the same meaning as in mb_ereg_replace().

Return Values

The resultant string or FALSE on error.



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.
