   } else {
      echo "No match found for uppercase characters.\n";
   }
?>

   $string = "Order1234: Your package will arrive soon.";
   $characters = "0123456789";

   $result = strpbrk($string, $characters);

   if ($result !== false) {
      echo "The first digit in the string is: $result\n";
   } else {
      echo "No digits found in the string.\n";
