However the following code works perfectly: $array1 = array ("a" => "green", "red", "blue"); $array2 = array ("b" => "green", "yellow", "red"); $result = array_intersect ($array1, $array2); if (false == empty($result)) { echo 1; } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=21942&edit=1
