 }
 }else { echo "Array is not an array or the string is not a string";
exit; }
}

function array_in_array($array1,$array2) {

if(is_array($array1)==1 AND is_array($array2)==1) {
$array_result = array();
 for ($i=0;$i<count($array1);$i++) {

  for ($j=0;$j<count($array2);$j++) {

   if($array1[$i]==$array2[$j]) {
