ID: 65237 Updated by: a...@php.net Reported by: jchan at malwarebytes dot org Summary: Array Equality Bug -Status: Open +Status: Not a bug Type: Bug Package: *General Issues Operating System: OSX & Linux Tested PHP Version: 5.3.26 Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php array('apple','banana') == array(1 => 'banana',2=>'apple') is the same as array(0 => 'apple', 1 => 'banana') == array(1 => 'banana',2=>'apple') So the doc won :) Previous Comments: ------------------------------------------------------------------------ [2013-07-10 17:32:11] jchan at malwarebytes dot org 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 this bug report at https://bugs.php.net/bug.php?id=65237&edit=1
