i saw this code some where and decided to use it. it works fine but i was told preg_replace has been deprecated that i should replace it with preg_replace_callback but once i did that it started showing me errors that my parameter 2 should be a call back, have tried to create a call back but got another error
<?php
function checkPost($result){
array(

return $result;
}
