Censor bad words with regexp

Published in: PHP 

URL: http://blog.otaku-anime.com/2008/04/29/filtro-de-palabras-en-php/

This function uses the power of regexp to check if some bad word are on the text, also offers the posibility to change those word for something else. Examples:

$texto = 'fuck off!'; filtrado($texto); returns true since a bad word has been found on the text filtrado($texto, '[censored]'); //returns [censored] off!

And because regexp, this will work with something like "fck off!". You can see a more detailed example here: http://www.otaku-anime.com/varios/filtro.php -- Example http://www.otaku-anime.com/varios/filtro.php?source -- Source code of the example

Plain TextExpand 
  1. <?php
  2. function filtrado($texto, $reemplazo = false)
  3. {
  4. 	$filtradas = 'fu?ck, shit'; //Define here your words to censor separated by comma (sorry for the badwords, it's just an example)
  5.  
  6. 	$f = explode(',', $filtradas);
  7. 	$f = array_map('trim', $f);
  8. 	$filtro = implode('|', $f);
  9.  
  10. 	return ($reemplazo) ? preg_replace("#$filtro#i", $reemplazo, $texto) : preg_match("#$filtro#i", $texto) ;
  11. }
  12. ?>
