Re: [PHP] Re: naughty words / filter

Try using str_ireplace, it is str_replace but is case insensitive.  
str_replace and str_ireplace both can take arrays as parameters for the 
needle, replacement value.  The string functions tend to be much faster 
than regular expressions, in any case you don't need the foreach..

this won't help your script work, but will tidy it up, but try using a
regular expression...
$dirty_words = array("|badword1|i","|badword2|i","|badword3|i"); //the i
will make it case insensetive, which is extra useful...
$message = preg_replace( $dirty_words, "****", stripslashes($message) );
echo $message;
