looking for the ord() function? You'd probably have to make an array for str_replace, though. So, it might be the long way around.

I saw a lot of functions using str_replace like:

[code]
<?php
function cleanA($str){
   $Aarray= array('À','Â','Á','Ã','Ä','Å');
   $str = str_replace($Aarray,'A',$str);
  
   $aarray = array('à','á','â','ã','ä','å');
   $str = str_replace($Aarray,'a',$str);

   return $str;
}
?>
[/code]
