Notas

Nota:
The internal encoding or the character encoding specified by mb_regex_encoding() will be used as the character encoding for this function.

Advertencia

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.

To highlight words in multi-byte text:



<?php

$s = 'Алабала';

$f = 'а';

echo preg_replace('/('.$f.')/iu', '<b>$1</b>', $s);
