递归地通过php中的数组修改叶子

Question

I hve the following array

$array = array(
  array(
    "name" => "Jacky O'Macky",
    "groups" => array (
      array (
        "Joseph O'Brien",
        "Jenna Williams"
      ),
      array (
        "Shaq O'Neil",
        "John Fabio"
      )
    )
  ),
  array(
    "name" => "Nate O'Grady",
    "groups" => array (
      array (
        "Joseph O'Brien",
        "Jenna Williams"
      ),
      array (
        "Shaq O'Neil",
        "John Fabio"
      )
    )
  )
);

I would like to go through each array and use the htmlspecialchars() to handle the names with apostrophe's and keep the same multi-dimensionally array structure.

Here is what I have so far

function htmlentities_array($array)
{
  if (is_array($array))
  {
    foreach($array as $key => $value)
    {
      if (is_string($value))
      {
        $array[$key] = htmlspecialchars($value);
      }
      else
      {
        $array[$key] = htmlentities_array($value);
      }
    }
  }
  else
  {
    $array = htmlspecialchars($array);
  }

  return $array;
}

I am calling this via $array = htmlentities_array(array) . It seems to only work on the first level.

Here you go

array_walk_recursive ($array, function(&$v,$k){
  $v = htmlspecialchars($v, ENT_QUOTES);
});

print_r($array);

Output

Array
(
   [0] => Array
    (
        [name] => Jacky O'Macky
        [groups] => Array
            (
                [0] => Array
                    (
                        [0] => Joseph O'Brien
                        [1] => Jenna Williams
                    )

                [1] => Array
    ....

Simple...
