Rather use rtrim(). Usage of chop() is not very clear nor consistent for people reading the code after you.

If you are searching for a function that does the same trick as chop in PERL, then you should just do the following code: $str = substr($str, 0, -1); ?> The question is: why isn't chop() an alias of the code above, rather than something which will trap developpers?

Another possible one would be to use this:
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.
