If you're trying to find out whether or not at least a single value of an array matches a value
in your haystack then use "array_intersect" instead of "in_array".
$needle = array(1,2);
$haystack = array(0,1,2);
echo "in_array: ".(int)in_array($needle, $haystack); // returns 0
echo "array_intersect: ".(int)array_intersect((array)$needle, $haystack); // returns 1
