#41178 [NEW]: Document order-preserving property of array_intersect, array_diff

From: olafb at google dot com Operating system: PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: Document order-preserving property of array_intersect, array_diff Description: ------------ array_intersect and array_diff are implemented s.t. the order of the elements of the first array is preserved. If the implementors consider that a feature, it should be documented such that users can rely on it. Otherwise, it should be documented that no assumption about order-preservations should be made. -- Edit bug report at http://bugs.php.net/?id=41178&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41178&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41178&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41178&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41178&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41178&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41178&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41178&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41178&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41178&r=support Expected behavior: http://bugs.php.net/fix.php?id=41178&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41178&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41178&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41178&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41178&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41178&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41178&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41178&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41178&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41178&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41178&r=mysqlcfg
