Question

I have one index.php , one.php file.

In one.php i have starting the session and setting the session var:

session_start(); 
if(isset($_GET['user'])){
    $_SESSION['user'] = $_GET['user'];
    }
function getUsername(){
  return $_SESSION['user'];
}

Im including one.php in index.php after im calling the function getUsername()
im not starting session in index.php

include_once('one.php');
echo getUsername();

But im not getting the session in index.php. Why ? im passing the the variable as

index.php?user=newuser .

is it not possible to get the session in all pages with out starting session . is it any possible method to get a global variable from any where, if i set it once..?

Answer 1

No it is not possible to get the session in all pages without starting session. So basically, you need to follow either of the following two ways:-

• Start the session in very new page, at the very beginning of the page, without any whitespace characters, using these lines of code:-

<?php

session_start();

// Other Lines of Code

• Include another common page (common.php) which has the line (session_start(); at the very beginning of that common page) at the beginning in every new page.

So basically, this particular statement (session_start();) is the heart of using the session.

Now according to your question, the page “one.php” must be included at the very beginning. So it should be working.

Hope it helps.
