How to use store and use session variables across pages?

Question

When one page is accessed, I would like to start a session and store a session variable:

<?php   session_start();    $_SESSION['myvar']='myvalue'; ?> 

Then from another page, I would like to check if that session variable has been stored:

<?php     session_start();     echo("1");     if(isset($_SESSION['myvar']))     {         echo("2");        if($_SESSION['myvar'] == 'myvalue')        {            echo("3");            exit;        }     }     ?> 

This code does not work for me.

Sessions Step By Step

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

   <?php session_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 protected]'; ?> 

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   ?>
