mb_ereg_replace(

     string$string,
     [string|null$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 in pattern.

replacement

The replacement text.

string

The string being checked.

options

The search option. See mb_regex_set_options for explanation.

Return Values

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.
