PHP Session not Saving

Question

I have this written at the very first line on every page of my website.

include("restd.php");

and restd.php contains the following lines :

@session_start();
if(isset($_SESSION['id']))
{
}
else
{
  header("location:index.php");
}

The problem i'm facing is that when ever i click or do something on my website. it logs me out and takes me to index.php.

im sure its something to do with the session. ive tried every single thing to avoid this problem but i ahve used restd.php because i dont want anyone to copy the url of someone and paste and get into the website.

anyone who is logged in only can view other's pages. if they arent logged in then they'll be redirected to index.php

EDIT : and guys a confusing thing is that all this is working fine on my testing server which is easyPHP-5.3.8.0 but this problem is coming up when i upload all the files to my server.

Answer 1

Your session directory (probably /tmp/) is not writable.

Check with session_save_path() if it is writable.

if (!is_writable(session_save_path())) {
    echo 'Session path "'.session_save_path().'" is not writable for PHP!'; 
}
