PHP Array Iterator to DIV - php

Question

I want to loop through the unknown depth array with RecursiveIteratorIterator in SELF::FIRST mode along with RecursiveArrayIterator.
If the array value is an array, I will open a DIV so the "subarray" will be inside this DIV. Something like
$array = array(
'key0' => '0',
'key1' => array(
'value0' => '1',
'value1' => '2',
),
'key2' => '3',
'key3' => array(
'value2' => '4',
'value3' => array(
'value4' => '5'
),
'value4' => array(
'value5' => '6'
),
),
);
Then the HTML should be:
<div>
<div>
<p>key0 is 0</p>
</div>
<div>
<p>key1</p>
<div>
<p>value0 is 1</p>
<p>value1 is 2</p>
</div>
</div>
<div>
<p>key2 is 3</p>
</div>
<div>
<p>key3</p>
<div>
<p>value2 is 4</p>
<p>value3</p>
<div>
<p>value4 is 5</p>
</div>
<p>value4</p>
<div>
<p>value5 is 6</p>
</div>
</div>
</div>
</div>
But the problem is my code can only close 1 <div> tag each time. I have no idea how to remember how deep was there. So I can close to a for loop and echo </div>.
My current code:
<?php
echo '<div>';
$iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($iterator_array), RecursiveIteratorIterator::SELF_FIRST);
$is_start = true;
$last_element = '';
foreach($iterator as $key => $value) {
if(is_array($value) && $is_start) {
echo '<div><p>' . $key . '</p>';
$is_start = false;
$last_element = end($value);
} elseif(is_array($value) && !$is_start) {
echo '</div><div><p>' . $key . '</p>';
$last_element = end($value);
} elseif(!is_array($value)) {
echo '<div><p>' . $key . ' is ' . $value . '</p></div>';
if($last_element == $value) {
echo '</div>';
}
}
}
echo '</div>';
?>

Use this recursive function
May be it will help you
get_div($array);
function get_div($arr) {
foreach($arr as $k => $a){
echo '<div>';
if(is_array($a)) {
echo "<p>".$k."</p>";
get_div($a);
} else {
echo "<p>".$k." is ".$a."</p>";
}
echo '</div>';
}
}
