在嵌套div中递归输出一个php数组？

Question

I have an array with a data structure like below

$array = array(
   'someKey' => array(
       'id' => 1,
       'string' => 'some key',
       'someKey2' => array(
            'id' => 1,
            'string' => 'some key two',
            'someKeyThree' => array(
                 'id' => 1,
                 'string' => 'some key three',
            ,
       ),
   ),
   'someOtherKey' => array(

   ),
);

What I would like to do is out every array as a nested div p structure,

<div>
    <p>someKey</p> // key of first array value
    <div>
          <p>someKey2</p>
          <div>
                 <p>SomeKeyThree</p>
          </div>
    </div>
</div>

I have tried using new RecursiveIteratorIterator(new RecursiveArrayIterator($this->getData(), RecursiveIteratorIterator::CHILD_FIRST));

and using that but I am having trouble as the end tag for div never ends up right. Also once the iterator reaches the bottom of an array with no array to go into I want it to stop iterating completely.

THanks

You have to call a function recursively.

function printUl($arr){
$output = "<ul>";
foreach ($arr as $key => $val){
  if (is_array($val)){
    $output .= printUl($val);
    continue;
  }
  else{
  $output .= "<li>".$val."</li>"

  }
$output .= "</ul>";
return $output;
}
}
