function menu_tree($lifo, $str)
{
if (sizeof($lifo) == 0)
return $str;

$clen = array_pop($lifo);

$str .= $clen . "-";
menu_tree($lifo, $str);
}

$list = array(1,4,5,6,7,8,9);

echo menu_tree($list, "Numbers: ");

I simplified my problem to the code above and the damn thing will not work like this 🙁

If I replace "$str .= $clen . "-";" with "echo $clen", then the output works nice... But I need a string, to write it to a file.

My system Windows NT localhost 5.1 build 2600, PHP Version 4.3.0, Zend Engine v1.3.0 and Apache/1.3.27 Server.

Help?
Thanks in advance...

So what is your problem, exactly?

try...

function menu_tree($lifo, $str)
{
if (sizeof($lifo) == 0)
return $str;

$clen = array_pop($lifo);

$str .= $clen . "-";
return menu_tree($lifo, $str);
}
