Are you sure Steve?

function level($n,$l=0,$d=false) {
if ($d) { return $l; }
else {
$ff=get_folders();
for ($i=0;$i<count($ff);$i++) {
if ($n==$ff[$i][0]) {
if ($ff[$i][4]!=0) {

Here he increments again before calling level()

$l++;
level($ff[$i][4],$l,$d);
}
else {

But here he has found what he wants and it should return on the next
recursion.

$d=true;
level($ff[$i][0],$l,$d);
}
}
}
}
}

I could be wrong, it wouldn't be the first time ;)
