Returning menu structure.

[eluser]Unknown[/eluser]
Hi Again, This little function loops though a multidimensional array and echos the data out as a multilevel list. It works a treat but instead of echoing the HTML list i would like it to return the HTML i have tried with a snippet below but it doesn't display the menu correctly.


Code that works fine.

Code:

/*
  * Render Cats into list.
  *************************/

function renderCatsList($arr)
{
     echo "<ul>";
  
     foreach ($arr as $cat)
     {
      echo "<li>";
      if(!isset($cat['children'])) $cat['children'] = array();
         echo $cat['cat_title'];

         if (count($cat['children']) > 0)
         {
          $this->renderCatsList($cat['children']);
         }

         echo "</li>";
     }

     echo "</ul>";

    }

But i would prefer this method but this does not work.

Code:

/*
  * Render Cats into list.
  *************************/

function renderCatsList($arr)
{
  $output = "<ul>";
  
     foreach ($arr as $cat)
     {
      $output .=  "<li>";
      if(!isset($cat['children'])) $cat['children'] = array();
         $output .= $cat['cat_title'];

         if (count($cat['children']) > 0)
         {
          $this->renderCatsList($cat['children']);
         }

         $output .= "</li>";
     }

        $output .= "</ul>";
            return $output;

    }

Nah, should be

Code:

$output .= $this->renderCatsList($cat['children']);

Recursive functions are always a joy ... NOT! The one above is simple enough, but whenever I find myself doing one of great complexity, I think it adds a couple of grey hairs to my head.
