Test array_intersect() function : usage variations - unexpected values for 'arr2' argument
--FILE--
<?php

 * Source code: ext/standard/array.c

/*
* Testing array_intersect() function by passing values to $arr2 argument other than arrays
* and see that function emits proper warning messages wherever expected.
* The $arr1 argument is a fixed array.
