  function compare($a, $b) {
    if ($a === $b) {
      return 0;
    }
    return ($a > $b) ? 1 : -1;
  }

  $array1 = ["a" => "green", "b" => "brown", "c" => "blue"];

  print_r(array_uintersect_assoc($array1, $array2, "strcasecmp"));
?>

Kodni bajarish natijasi:

phpArray
(
  [a] => green
  [c] => blue
)

Misol

Raqamli qiymatlar bilan solishtirish:
