I am trying to get my data which is hierarchically set up with a tree traversal model into an < ul> in order to show on my site.

Here is my code:

Better Render Tree Function that worked for me (php function to prepare html source for use in jsTree jQuery plugin) instead of the Henrik Opel's one:

function MyRenderTree ( $tree = array(array('name'=>'','depth'=>'')) ){

$current_depth = 0;
$counter = 0;

$result = '
';

foreach($tree as $node){
    $node_depth = $node['depth'];
    $node_name = $node['name'];
    $node_id = $node['category_id'];

    if($node_depth == $current_depth){
        if($counter > 0) $result .= '';            
    }
    elseif($node_depth > $current_depth){
        $result .= '
';
        $current_depth = $current_depth + ($node_depth - $current_depth);
    }
    elseif($node_depth < $current_depth){
        $result .= str_repeat('
',$current_depth - $node_depth).'';
        $current_depth = $current_depth - ($current_depth - $node_depth);
    }
    $result .= '
';
    ++$counter;
}
 $result .= str_repeat('
',$node_depth).'
