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 this bug report at https://bugs.php.net/bug.php?id=73617&edit=1
