This function corresponds more or less to the PERL chomp() function.

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.
