Rather use rtrim(). Usage of chop() is not very clear nor consistent for people reading the code after you.
Descrizione
Questa funzione è sinonimo di: rtrim().
Nota:
chop() è differente rispetto alla omonima funzione di Perl
chop(), la quale rimuove l'ultimo carattere della stringa.

If you are searching for a function that does the same trick as chop in PERL, then you should just do the following code:
<?php
$str = substr($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:
<?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.
