Recursive function for php, mysql, suckerfish

This is code snippet for php recursive function that works with mysql and suckerfish, for instance if we have database with table named menu

=========================================
id | parent_id | name     | link
=========================================
1  | 0         | home     | index.php
2  | 0         | about us | about_us.php
3  | 2         | carreer  | career.php
4  | 2         | jobs     | jobs.php
==========================================

and we want to use jquery suckerfish menu to display it.

The sql query and display the menu

$query = "SELECT id, name, parent_id, link FROM `menu`";
$result = mysql_query($query) or die( $query);
while ($row = mysql_fetch_object($result)) {
$data[$row->parent_id][] = $row;
}

echo get_menu($site_url,$data);

The php recursive function

function get_menu( &$site_url, $data, $parent = 0) {
	      $i = 1;
		  $html = '';
	      if (@$data[$parent]) { 
		      if($parent > 0)$html = " 
";
		      $i++;
		      foreach ($data[$parent] as $v) {
			       $child = get_menu( $site_url, $data, $v->id);
			       $html .= "
";
					   if($parent > 0) $html .= ''.$v->name.'';
					   else $html .= ''.$v->name.'';
					   if ($child) {
						   $i--;
						   $html .= $child;
					   }
			       $html .= '
';
		      }
			  if($parent > 0)$html .='
';
			  $html .= "
";
		      return $html;
	      } 
        else {
		      return false;
	      }
      }
