Note Submitter: lgomez edgeracing com ---- Here's a way of replacing any collection of words from a string. Good for filtering bad words. I don't know if it can be compacted even more. <?php function filter($str,$words,$replacement='*'){ foreach($words as $word){ $str=preg_replace("/\\b$word\\b/i",' '.str_repeat($replacement,strlen($word)).' ',$str); } return $str; } $bad_words=array('butt','poop','crap'); $text='One thing to take note bhjbdscrapmkjv of is that if you use poop as paint, you may not get the crap you expect butt.'; echo filter($text,$bad_words); ?>
