[omardealo]

HELLO ,

i try discovery of banned words when users posted new post , but i have a problem only Only the discovery of English words, I think that the problem is in the Arabic language encoding , I tried to solve the problem by

PHP Code:

iconv("windows-1256", "utf-8",$string ); 


but don't work , Are there any suggestions ?

$wordss = "هالو|مرحبا|google.com";
$bwords = explode("|", $wordss);   
//$string = $vbulletin->GPC['message'];  
$string = 'BLA BLA مرحبا BLA BLA google.com BLA BLA BLA ';  
$matchFound = preg_match_all(  
                "/\b(" . implode($bwords,"|") . ")\b/i",   
                $string,   
                $matches  
              );  
$words = array_unique($matches[0]);   
print_r($words);

output : google.com
but Must be : google.com,مرحبا
