Actually, PHP's chop() acts just as perl's chomp(). The above user-contributed example does not act enough like perl's chop(), however. An important part of perl's chop() is that it returns the chop()ed character. Here's how to get perl-style chop()s [let's call it chomp() just to bring this whole mess full-circle] <?php function chomp(&$string) { if (is_array($string)) { foreach($string as $i => $val) { $endchar = chomp($string[$i]); } } else { $endchar = substr("$string", strlen("$string") - 1, 1); $string = substr("$string", 0, -1); } return $endchar; } ?> --was-- Actually, PHP's chop() acts just as perl's chomp().
