Total users as i have by reff tree

[dushtu.bor]

Please tell me why it gives me always zero value?

<?php
$total =0;

		$memid = $_POST['username'];
		$leg = $_POST['leg'];

mysql_connect ("host", "usr", "paswd") or die ('Error: ' .mysql_error());
mysql_select_db ("dbname");
function getTotalLeg($memid,$leg){	
$sql="select $leg from `users` where `username`='$memid' ";

$res=mysql_query($sql);
$row=mysql_fetch_array($res);

global $total;

$total = $total+mysql_num_rows($res);
            if($row['$leg']!=''){
                getTotalLeg ($row['$leg'],'lname');
                getTotalLeg ($row['$lrg'],'rname');
            }         
return $total;
}
echo $total;
?>

Please, solve it. I want to count how much i have in my left or right, sum of total in binary tree.

That looks like a very convoluted piece of code. I'm sure there's an easier way of doing what you want. Could you please write out in steps (1. ... 2. ... etc), what you're trying to achieve.

I got the problem, i didn't call the function.
