I'm getting the following warning;
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\xampp\htdocs\ep\login.php:1) in C:\xampp\htdocs\ep\login.php on line 2
If i comment session_start(), everthing works fine. Where is the actual problem?
Here is my code;
<?
session_start();
include "config.php";
global $c;
require('functions.php');
if($_POST)
{
$username=uc($_POST['username']);
$password=uc($_POST['password']);
/*if($_POST['code']!=$_SESSION['string'])
{
header("Location: login.php?error=1");
}
else
{*/
$query = mysql_query("SELECT username,password FROM tb_users WHERE username = '$username'") or die(mysql_error());
if(mysql_num_rows($query) == 0)
{
echo "asdsadasdsad";
header("Location: index.php?error=2");
}
else
{
$data = mysql_fetch_array($query);
if($data['password'] != $password)
{
header("Location: login.php?error=2");
}
else
{
$query = mysql_query("SELECT username,password FROM tb_users WHERE username = '$username'") or die(mysql_error());
$row = mysql_fetch_array($query);
$nick=$row['username'];
$pass=$row['password'];
setcookie("usNick",$nick,time()+7776000);
setcookie("usPass",$pass,time()+7776000);
$lastlogdate=time();
$lastip = getRealIP();
$querybt = "UPDATE tb_users SET lastlogdate='$lastlogdate', lastiplog='$lastip' WHERE username='$nick'";
mysql_query($querybt) or die(mysql_error());
$checkuser = mysql_query("SELECT username FROM tb_acchold WHERE username='$nick'");
$username_exist = mysql_num_rows($checkuser);
