[PHP-NOTES] note 130632 added to function.array-key-exists

You just did a Control/Command+F  to look for multidimensional support and you found this. I'm posting both the key and value on their respective documentation pages.

<?php
function in_multi_array_key($needle, $array)
{//2020-10-05
 $r = false;

 foreach ($array as $k1 => $v1)
 {
  if (is_array($v1))
  {
   $r = in_multi_array_key($needle, $v1);
   if ($r) {break;}
  }
  else if ($k1 === $needle) {$r = true; break;}
 }

 return $r;
}
?>
