Bug #73617 [NEW]: Array diff output is wrong.

From: hello at bweston dot me Operating system: Linux PHP version: Irrelevant Package: Arrays related Bug Type: Bug Bug description:Array diff output is wrong. Description: ------------ So I have the following ``` <?php var_dump(array_diff( [ 'q1' => true, 'q2' => true, 'q3' => false, 'q4' => false, ], [ 'q1' => false, 'q2' => false, 'q3' => false, 'q4' => false, ] )); ``` Which produces: (https://3v4l.org/WSs2s) ``` array(2) { ["q1"]=> bool(true) ["q2"]=> bool(true) } ``` Which is fine however with just one change it isn't seen. The following produces an empty array yet there is a change. (https://3v4l.org/DlnBr) ``` <?php var_dump(array_diff( [ 'q1' => true, 'q2' => true, 'q3' => false, 'q4' => false, ], [ 'q1' => false, 'q2' => true, 'q3' => false, 'q4' => false, ] )); ``` -- Edit bug report at https://bugs.php.net/bug.php?id=73617&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73617&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73617&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73617&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73617&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73617&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73617&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73617&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73617&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73617&r=support Expected behavior: https://bugs.php.net/fix.php?id=73617&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73617&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73617&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73617&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73617&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73617&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73617&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73617&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73617&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73617&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73617&r=mysqlcfg
