#25829 [Opn->Bgs]: For loops against the alphabet don't function properly

ID: 25829 Updated by: elmicha@php.net Reported By: tim at timcrider dot com -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: Red Hat 9.0 PHP Version: 5CVS-2003-10-10 (dev) New Comment: It's a feature, not a bug. See <http://www.php.net/language.operators.increment>. Previous Comments: ------------------------------------------------------------------------ [2003-10-10 16:55:37] tim at timcrider dot com Description: ------------ When trying to loop 'a' through 'z' using for ($i = 'a'; $i < 'z'; $i++) print $i; it loops a-y as it should, but when you try for ($i = 'a'; $i <= 'z'; $i++) print $i; instead of going a-z it goes a-yz doubling up the letters after a-z a-z aa-az ba-bz ca-cz ... etc I know this breaks under php5, and under php4. Reproduce code: --------------- for ($i = 'a'; $i < 'z'; ++$i) { print "$i\n"; } and for ($i = 'a'; $i <= 'z'; ++$i) { print "$i\n"; } Expected result: ---------------- abcdefghijklmnopqrstuvwxyz (seperated by new lines) Actual result: -------------- abcdefghijklmnopqrstuvwxyzaaabacadaeaf....yxyyyz ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25829&edit=1
