[Solved] create html list from array with levels

by


If you need list with ul, li tags, try to use this code. It should work.

$lastLvl = 1;
echo '<ul>';
foreach ($array as $object) {
    if ($object->lvl < $lastLvl) {
        for ($i = 1; $i <= ($lastLvl - $object->lvl); $i++)
            echo '</ul>';
    }

    if ($object->lvl > $lastLvl) {
        for ($i = 1; $i <= ($object->lvl - $lastLvl); $i++)
            echo '<ul>';
    }
    echo '<li>', $object->name, '</li>';

    $lastLvl = $object->lvl;
}
for ($i = 1; $i <= $lastLvl; $i++)
    echo '</ul>';
