help with preg_replace

[helraizer]

Hi folks,

 

I have a piece of code:

 

$dirty = array('bad words here', 'more bad words here', 'this is another bad word');
foreach($dirty AS $bad_word){
                        $text = preg_replace("/$bad_word/i","****", $text);
                        }    

 

Which works fine but how would I do it so that instead of replacing it with **** it merely gets rid of it completely?

 

Hope that makes sense,

Sam

change "****" to empty string "".

And you should use str_ireplace() instead of preg_replace(). Much faster.

Always preg_quote variables that are going to be used in regular expressions.
