PHP session doesn't persist on new server

Question

First off, I did read at least 10 similarly named questions and answers and did not resolve the issue.

I had a working AJAX-based login script, but now that I've copy-pasted the entire site to new hosting, it doesn't work.

The process is simple.

Javascript sends login data to ajax.php , where this happens:

session_start();

//check database

$_SESSION['isloggedin']=1;
//if I var_dump($_SESSION) here, it prints out `array{'isloggedin' => 1}`

echo "ok";

Then Javascript redirects to index.php , which is currently:

session_start();
var_dump($_SESSION);

But here, $_SESSION is an empty array!

If I do echo session_id(); on both pages, it prints out the same value.

What could possibly be the issue here?

Remember, it worked perfectly on a different server.

Answer 1

Have you tried basic session increment test by reloading one page in the browser? For example:

<?php
session_start();
if (!isset($_SESSION['count'])) {
  $_SESSION['count'] = 0;
} else {
  $_SESSION['count']++;
}
?>

Is it working?

If you store session data in files (default PHP configuration): Can you access folder, where session files are stored? Is anything stored in session file, that assigned to your session?

Answer 2

first thing is in which page you use session you have to write first line is session_start() ok?

please try this i hope your problem solve
