Alias Of rtrim Function

chop() is different than the Perl chop() function, which removes the last character in the string. Another possible one would be to use this:

<?php
function chup(){
$ar=Array();
foreach(func_get_args() as $b) {
push($ar,$b[strlen($b)-1]);
&$b[strlen($b)-1]='';
}
return $ar;
}
?>

If you wanted to perl-chop a va list of strings and return the removed chars. Obviously you can easily mod it for va list arrays of strings and the like.
