Help with word filter

[EchoFool]

Hey,

 

I have a word filter which is dectecting strings that are only embedded in words. Which i don't want it to do.

 

For example:

 

If i want to filter "FR" and some one puts france - it flags it because france contains FR.

 

How do i make it only look for "FR" on its own seperated from a word instead of it flagging nearly all words with the two letters together?

 

Heres my filter:

 

 

$text = 'testing';  //this should not return 1
  // fill this array with the bad words you want to filter and their replacements
     $bads = array ("test");

                
foreach($bads as $key => $search_needle) {

   if(stristr($text, $search_needle) == TRUE) {
       return(1);
       break;
        }
    }

if (preg_match('~\b'.$search_needle.'\b~i',$text)) {

 

on a sidenote, if you're looking for something somewhat more robust, check out this word filter function I created a while back.  Basically it lets you specify bad words and define masks for them.
