Req #64854 [NEW]: array_key_exists( array('key1', 'key2', 'key3'), $array);

From: bensor987 at neuf dot fr Operating system: All PHP version: Irrelevant Package: Arrays related Bug Type: Feature/Change Request Bug description:array_key_exists( array('key1', 'key2', 'key3'), $array); Description: ------------ Why can't we give an array as the first parameter of array_key_exists() ? I have a few cases where it would be useful. Especially when checking $_POST, $_GET or $_REQUEST arrays (for instance). Test script: --------------- $array_to_test = array( 'key1' => 1, 'key2' => 1, 'key3' => 1 ); $array_keys = array( 'key1', 'key2', 'key3'); var_dump( array_key_exists( $array_keys, $array_to_test ) ); var_dump( (array_key_exists( 'key1', $array_to_test ) && array_key_exists( 'key2', $array_to_test ) && array_key_exists( 'key3', $array_to_test )) );// The same as above, but much longer. Expected result: ---------------- bool(true) bool(true) Actual result: -------------- bool(false) bool(true) -- Edit bug report at https://bugs.php.net/bug.php?id=64854&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64854&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64854&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64854&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64854&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64854&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64854&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64854&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64854&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64854&r=support Expected behavior: https://bugs.php.net/fix.php?id=64854&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64854&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64854&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64854&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64854&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64854&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64854&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64854&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64854&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64854&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64854&r=mysqlcfg
