3 level array in php to organize data [closed]

Answer 1

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;?>

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.

Answer 2

Have you try to use 3 foreach()

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