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)
