Hello, I have the following problem:

I want my function to return a value, $l, using the following function:

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) {
$l++;
level($ff[$i][4],$l,$d);
}
else {
$d=true;
level($ff[$i][0],$l,$d);
}
}
}
}
}

The function does not return $l, however. If I replace "return $l" in
the first line of the function with "print $l", the right value for $l
appears on the screen.

Does anyone know a solution to this problem?

Best,

Rienk
