I want create a three-level array in php, with example data for developing purposes, I have this:

$data = array(
array(1 => array("A ROW GREENS", array(
    "A1" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg"),
    "A2" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg"),
    "A3" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg")
))),
array(2 => array("A ROW BLUE",array(
    "A1" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg"),
    "A2" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg"),
    "A3" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg")
))),

);

How you can see, this is the structure:

Element:[ID -> Title][IDSubitem1->URL, IDSubitem2->URL2...]
Element:[ID -> Title][IDSubitem1->URL, IDSubitem2->URL2...]
Element:[ID -> Title][IDSubitem1->URL, IDSubitem2->URL2...]

I need to print a <ul> with the Titles (using id for identifier them) and print other <ul> tags for show or hide the subitems or the selected parent.

<ul id="parent">
    <li id="1">A ROW GREENS</li>
    <li id="2">A ROW BLUE</li>
</ul>

<ul id="child1">
    <li id="child1-A1">http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg</li>
    <li id="child1-A2">http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg</li>
    <li id="child1-A3">http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg</li>
</ul>

<ul id="child2">
    <li id="child2-A1">http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg</li>
    <li id="child2-A2">http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg</li>
    <li id="child2-A3">http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg</li>
</ul>

You can achieve your expected outcome like below:-

<?php
$data = array(
array(1 => array("A ROW GREENS", array(
    "A1" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg"),
    "A2" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg"),
    "A3" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg")
))),
array(2 => array("A ROW BLUE",array(
    "A1" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg"),
    "A2" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg"),
    "A3" => array("http://flexslider.woothemes.com/images/kitchen_adventurer_cheesecake_brownie.jpg")
))));

$parent_data = '';
$child_data = '';
foreach($data as $dat){
    foreach($dat as $key=>$da){
        $parent_data .="<li id ='".$key."'>".$da[0]."</li>";
        $child_data .="<ul id='child".$key."'>";
        foreach ($da[1] as $k=>$v){
             $child_data .="<li id='child".$key."-".$k."'>".$v[0]."</li>";
        }
        $child_data .="</ul>";
    }

}
?>
<ul id="parent"><?php echo $parent_data;?></ul><?php echo  $child_data;?>

Output:- https://eval.in/656522

Note:- The code will only work for the given array structure (element can be more, no problem), But if array structure is changed then code will not work.

Have you try to use 3 foreach()

foreach($data as $level1)
{
  foreach(level1 as $level2)
  {
    foreach(level2 as $level3)
    {
