Code doesn`t work in Function Block

[khalsaji99]

Hey guys ! Code works when not put in functions block. Why ?
Please help ?

<?php
function DB_connect()
{
         global $server, $dbuser, $dbpw, $db;

     $link = mysql_connect("localhost", "root");

     if (!$link) die ("Connection fail to MySql !");

     mysql_select_db("login",$link) or die ("Couldn't connect to Database !");

     return $link;
}
function SqlValidateUser($id,$psw)
{
        $SQL = "SELECT * FROM securelogin";

    $link = DB_connect();
    $result = mysql_query($SQL,$link) or die("Couldn't execute query.");
	printf("ID: %s<br>\n", mysql_result($result,0,"id"));
	printf("PASSWORD: %s<br>\n", mysql_result($result,0,"passwd"));
}

?>

Is it dying or just failing silently?

Are you sure you are calling SqlValidateUser?
