How to use store and use session variables across pages?

Solution 1:

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.

Solution 2:

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 

?>
