Anyone have a look at this

[thoand]

A while back ago I created a simple tree walking using recursive.
and I got alot of feedback and solutions, but now when I mingle it with other code I have lost controll, can anybody help me see through the code below and see what is wrong, please!

best regards Thomas

Code:
It returns the results but I get alot of error messages at first:

<?
$tree = buildTree(0,0,'-');
foreach($tree as $leaf) {echo $leaf . "<br>\n";}

function buildTree($id = 0, $cnt = 0, $idnt = '*', $running = 0) {
global $db;
//if we are not in a recursive loop
if(!$running || !is_numeric($running)) {
if(!is_numeric($id)) {return -1;}
if(!is_numeric($cnt)) {return -1;}
if(!is_numeric($cnt)) {return -1;}
} //end if
$retVal = array();

$names = $db->get_results("SELECT * FROM names WHERE parent = ". $id ."");

foreach ($names as $name) {
    array_push($retVal,(str_repeat($idnt,$cnt) . $name->name."$running")); 
    $retVal = array_merge($retVal,buildTree($name->id, $cnt + 1, $idnt, 1));
}
return($retVal);

} //end build tree
?>

$names = $db->get_results("SELECT * FROM names WHERE parent = ". $id ."");
//add this line
$names=is_array($names)?$names:array();
foreach ($names as $name) {
There is a chance that $names will not be an array. I think that is the problem
