How to use store and use session variables across pages?

Sessions Step By Step

1. Defining session before everything, No output should be before that, NO OUTPUT

   <?phpsession_start();?>

2. Set your session inside a page and then you have access in that page. For example this is page 1.php

   <?php   //This is page 1 and then we will use session that defined from this page:    session_start();    $_SESSION['email']='email@example.com';?>

3. Using and Getting session in 2.php

    <?php//In this page I am going to use session:  session_start();  if($_SESSION['email']){  echo 'Your Email Is Here!  :) ';  } ?>

NOTE: Comments don't have output.

All you want to do is write --- session_start(); ----- on both pages..

<!-- first page --><?php  session_start();   $_SESSION['myvar'] = 'hello';?><!-- second page --><?php    session_start();    echo $_SESSION['myvar']; // it will print hello ?>

Reasoning from the comments to this question, it appears a lack of an adjusted session.save_path causes this misbehavior of PHP’s session handler. Just specify a directory (outside your document root directory) that exists and is both readable and writeable by PHP to fix this.
