How do I call a php function twice on the same page?

Hello everyone,

I'm new of course... PHP Functions  

Error when I use the function twice.
Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /includes/fb.php on line 12

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /includes/fb.php on line 14

Here is the code.  I'm trying to call the function twice on the same page - info.php



$var1 = 2;
add_rating ($var1); // Should display member 2

<br />

$var2 = 75;
add_rating ($var2); // Should display member 75



If I use the function only "once" like this...  it works...


$var1 = 2;
add_rating ($var1); // Should display member 2


[Here is the function code]


function add_rating ($usernum) {

require_once('Connect/xxxx.php'); // T

mysql_select_db($database_xxxx, $xxxx);
$query_username = "SELECT username, joindate FROM Members WHERE usernum = '$usernum'";
$username = mysql_query($query_username, $usell) or die(mysql_error());
$row_username = mysql_fetch_assoc($username);
$totalRows_username = mysql_num_rows($username);

$rating = $row_username['username'];
$rating .= " <b>";
$rating .= $row_username['joindate'];
$rating .= "</b>";

echo $rating;

return $rating;

you use require_once('Connect/xxxx.php');

That is if page Connect/xxxx.php is already included the file is not included again.

You sholud place the mysql_select_db($database_xxxx, $xxxx); inside Connect/xxxx.php

put the mysql_select_db function in the same file as the mysql_connect function  like

$db = mysql_connect("localhost","username","pass");
