Write a PHP program to check two given integers and return the value whichever value is nearest to 13 without going over

<?php
function test($x, $y)
{
  if ($x > 13 && $y > 13) return 0;
  if ($x <= 13 && $y > 13) return x;
  if ($y <= 13 && $x > 13) return y;
  return $x > $y ? $x : $y;
}

echo (test(4, 5))."\n";
echo (test(7, 12))."\n";
echo (test(10, 13))."\n";

echo (test(17, 33))."\n";
