<?php
ob_start();
@session_start();
require_once ("check.php");
createsessions($username,$password,$userid,$projectid,$projectname,$filename,$size,$allocatedmemory,$answer,$usedmemory,$Remainingmemory,$result,$data3,$abc);
include 'connection.php';
$query= mysql_query("SELECT projectassign FROM projectassign where userid=(select userid from users where username='$username' and role='2')");
mysql_error();
$num=mysql_num_rows($query);  
 ?>
