#20261 [NEW]: str_rot13() changes too much

From: jeroen@unfix.org Operating system: Linux (at least) PHP version: 4.2.3 PHP Bug Type: Strings related Bug description: str_rot13() changes too much a) str_rot13() changes it's given variable. b) str_rot13() changes OTHER variables. 8<---------------------------- $ cat test.php <?php $first = "boo"; $second = $first; $rot = ""; echo "1: ".$first."\n"; echo "2: ".$second."\n"; echo "3: ".$rot."\n"; $rot = str_rot13($second); echo "1: ".$first."\n"; echo "2: ".$second."\n"; echo "3: ".$rot."\n"; ?> --------------------------->8 8<----------------------- $ php4 -q test.php 1: boo 2: boo 3: 1: obb 2: obb 3: obb ----------------------->8 The changing of 1 is quite odd (subbug B) and very annoying. The changing of 2 is probably because it happens in place. Either way $first shouldn't be touched at all. This is on Debian Linux/unstable, but others are probably affected too. -- Edit bug report at http://bugs.php.net/?id=20261&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=20261&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=20261&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=20261&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=20261&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=20261&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=20261&r=support Expected behavior: http://bugs.php.net/fix.php?id=20261&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=20261&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=20261&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=20261&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=20261&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=20261&r=dst IIS Stability: http://bugs.php.net/fix.php?id=20261&r=isapi
