OK, so this is a simple word filter I made for use in any application like
plug-n-play. Quite simple and easy to use. 
So here goes. Following this is an example on how to use it. 

Filter.php: 

<?php 

This function does all the work. If $replace is 1 it will replace all bad words with the wildcard replacements.  If $replace is 0 it will not replace anything. In either case, it will return 1 if it found bad words or 0 otherwise.Be sure to fill the $bads array with the bad words you want filtered. 

***************************************************************/ 

function Filter(&$text, $replace) 
       { 
    //fill this array with the bad words you want to filter and their replacements 
    $bads = array ( 
        array("Fool","F**l"), 
        array("crap","c***") 
    ); 

    if($replace==1) 
       { 
              //we are replacing 
        $remember = $text; 
         
    for($i=0;$i<sizeof($bads);$i++) 
       { 
    //go through each bad word 
    $text = eregi_replace($bads[$i][0],$bads[$i][1],$text); //replace it 
    } 

    if($remember!=$text) return 1;                 //if there are any changes, return 1 
         
    } else {                             

        //we are just checking 
        for($i=0;$i<sizeof($bads);$i++) 
              { 
        //go through each bad word 
        if(eregi($bads[$i][0],$text)) return 1; //if we find any, return 1 
        }     
         
    } 
} 

?> 

Example1.php 

<?php 

include('Filter.php'); 

// This will replace all bad words with their replacements.$any is 1 if it found any 
$result = Filter($wordsToFilter,1); 

//this will not repace any bad words but instead will only search for them. $any is 1 if it found any 
$result = Filter($wordsToFilter,0); 

?>
