Question

i have an array , like this

Array ( [id] => 1 [did] => 1 [title] => first link [link] => link.com ) 
Array ( [did] => 1 [title] => second link [link] => link2.com ) 
Array ( [id] => 2 [did] => 2 [title] => forum 1 [link] => forum.php ) 
Array ( [did] => 2 [title] => forum 2 => viewtopic.php ) 
Array ( [did] => 2 [title] => register [link] => register.php )

and i want to extract it , like this

- first link
-- seconde link
- forum 1
-- forum 2
-- register

id , is main , and did , is parent in this array. any way? i want this output :

<ul>
    <li><a href="link.com">first link</a>
        <ul>
            <li><a href="link2.com">seconde link</a></li>
        </ul>
    </li>
    <li><a href="forum.php"> forum 1</a>
        <ul>
            <li><a href="viewtopic.php"> forum 2</a></li>
            <li><a href="register.php"> register</a></li>
        </ul>
    </li>
</ul>

What have you tried? Start by using a foreach loop and conditions to check child-parent relation. — Ofir Baruch

The structure isn't that clean, but sometime the data doesn't come in clean. Something like this should work (although the <?= short tag may cause issues if that isn't set up in your environment). I used colons instead of braces only because I think it is easier to read in this kind of mixed code.

<ul>
<?php foreach ($arr as $item): ?>
    <li><a href="<?=$item['link']?>"><?=$item['title']?></a>
        <ul>
        <?php 
            foreach ($arr as $item2): 
               if ((array_key_exists('did', $item2) && ($item2['did'] == $item['id'])):
        ?>
             <li><a href="<?=$item2['link']?>"><?=$item2['title']?></a></li>    
        <?php
               endif;
             endforech;
        ?>
        </ul>
    </li>
<?php endforeach;?>
</ul>
