Question

I’m trying to actually loop a function with a different function parameter each time which is obtained by the function itself;

Im using a variable $login_name as function parameter which was submitted by a form. So I want to change this parameter by the function itself. absurd? is there any alternative?

Here’s my function

$login_name = "U00001";
while (!isset($end)) {
    function getcount($login_name) {
        $get_node = mysql_query("SELECT * FROM b_userbase WHERE login_name='$login_name'");
        while ($row_node = mysql_fetch_array($get_node)) {
            $node = $row_node["user_node"];
            $placement = $row_node["user_placement"];
        }
        $current_count = mysql_query("SELECT * FROM f_user_matching WHERE u_m_mem='$placement'");
        while ($get_count = mysql_fetch_array($current_count)) {
            $get_left_current = $get_count["u_m_left_current"];
            $get_left_total = $get_count["u_m_left_total"];
            $get_right_current = $get_count["u_m_right_current"];
            $get_right_total = $get_count["u_m_right_total"];
            $update_left_current = $get_left_current + 1;
            $update_right_current = $get_right_current + 1;
            $update_left_total = $get_left_total + 1;
            $update_right_total = $get_right_total + 1;
        }
        if ($node == "L") {
            $increase_qry = mysql_query("UPDATE f_user_matching 
                                            SET u_m_left_current= '{$update_left_current}',
                                                u_m_left_total ='{$update_left_total}'
                                            WHERE u_m_mem ='{$placement}' ");
        }
        if ($node == "R") {
            $increase_qry = mysql_query("UPDATE f_user_matching 
                                            SET u_m_right_current= '{$update_right_current}',
                                                u_m_right_total ='{$update_right_total}'
                                            WHERE u_m_mem ='{$placement}' ");
        }
        $login_name = $placement;
        if ($login_name == "IM000001") {
            $end = 1;
        } else {
            $login_name = $placement;
        }
        global $login_name;
    }
    $count = getcount($login_name);
}

Where is the problem?

I dont understand what you ar doing, so you might be trying to do something different that I do not know about, but if what you need is an recursive function then this is not the way. You dont define the function inside a while-loop, the function should be defined as a normal function, but in can call itself whit a different result.

This is how your function would be as recursive.
This is not tested code

    <?php

 $login_name = "U00001";
 $count = getcount($login_name);

 function getcount($login_name) {
        $get_node = mysql_query("SELECT * FROM b_userbase WHERE login_name='$login_name'");
        while ($row_node = mysql_fetch_array($get_node)) {
            $node = $row_node["user_node"];
            $placement = $row_node["user_placement"];
        }
        $current_count = mysql_query("SELECT * FROM f_user_matching WHERE u_m_mem='$placement'");
        while ($get_count = mysql_fetch_array($current_count)) {
            $get_left_current = $get_count["u_m_left_current"];
            $get_left_total = $get_count["u_m_left_total"];
            $get_right_current = $get_count["u_m_right_current"];
            $get_right_total = $get_count["u_m_right_total"];
            $update_left_current = $get_left_current + 1;
            $update_right_current = $get_right_current + 1;
            $update_left_total = $get_left_total + 1;
            $update_right_total = $get_right_total + 1;
        }
        if ($node == "L") {
            $increase_qry = mysql_query("UPDATE f_user_matching 
                                            SET u_m_left_current= '{$update_left_current}',
                                                u_m_left_total ='{$update_left_total}'
                                            WHERE u_m_mem ='{$placement}' ");
        }
        if ($node == "R") {
            $increase_qry = mysql_query("UPDATE f_user_matching 
                                            SET u_m_right_current= '{$update_right_current}',
                                                u_m_right_total ='{$update_right_total}'
                                            WHERE u_m_mem ='{$placement}' ");
        }
        $login_name = $placement;
        if ($login_name != "IM000001") {
            $login_name = $placement;
            $count = getcount($login_name);
        }
        global $login_name; // Dont know why you want this one?

    }

    ?>

Dont know why you have *global $login_name;* at the end. Do you want the function to return something or just perform the UPDATE in the database?
