From: jchan at malwarebytes dot org Operating system: OSX & Linux Tested PHP version: 5.3.26 Package: *General Issues Bug Type: Bug Bug description:Array Equality Bug
Description: ------------ When comparing 2 arrays in an if statement, array equality according to the documentation (http://www.php.net/manual/en/language.operators.array.php) does not work. According to the docs, order should not matter, but when comparing 2 arrays directly it does. Test script: --------------- <?php // based off of http://www.php.net/manual/en/language.operators.array.php $a = array("apple", "banana"); $b = array(1 => "banana", "0" => "apple"); ## WORKS ## var_dump($a == $b); // bool(true) var_dump($a === $b); // bool(false) var_dump(array("apple", "banana") == array(1 => "banana", "0" => "apple")); // bool(true) ## FAILS? ## if (array('apple','banana') == array(1 => 'banana',2=>'apple')) echo "they are equal.\n"; else echo "They are not equal.\n"; // this is the response I get ## yet if I do: if ($a == $b) echo "they are equal.\n"; // this is the response I get... else echo "They are not equal.\n"; ?> Expected result: ---------------- bool(true) bool(false) bool(true) they are equal. they are equal. Actual result: -------------- bool(true) bool(false) bool(true) They are not equal. they are equal. -- Edit bug report at https://bugs.php.net/bug.php?id=65237&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65237&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=65237&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65237&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65237&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65237&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65237&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65237&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65237&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65237&r=support Expected behavior: https://bugs.php.net/fix.php?id=65237&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65237&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65237&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65237&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65237&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65237&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65237&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65237&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65237&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65237&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65237&r=mysqlcfg
