How to use $GLOBALS to share variables across php files?

I have a file, index.php that produces a link to a page that I want my user to only be able to access if some $var == True.

I want to be able to do this through the $GLOBALS array, since my $_SESSION array is already being filled with instances of a specific class I want to manipulate further on.

My index.php page:

<?php

    $var = True;

    $GLOBALS["var"];

    echo "<p><a href='next.php'>Click to go to next page</a></p>";

?>

My next.php page:

<?php

        if($GLOBALS["var"] == False)
            exit("You do not have access to this page!");
        else
            echo "<p>You have access!</p>";

?>

Currently, next.php is echoing the exit text. Am I accessing/assigning to the $GLOBALS array correctly? Or am I not using it properly?

Thanks!

EDIT: So I've tried some of the suggestions here. This is my new index.php:

<?php

    $GLOBALS["var"] = True;

    echo "<p><a href='next.php'>Click to go to next page</a></p>";

?>

My next.php:

<?php

    if($GLOBALS["var"] == False)
        exit("You do not have access to this page!");
    else
        echo "<p>You have access!</p>";

?>

However, I'm still running into the same issue where the exit statement is being printed.

It's much better to use sessions for this, since they are more secure and exist for this purpose. The approach I would recommend, is starting a new separate session array.

session_start();
$_SESSION['newSession']['access'] = true;

Then to access it use the same key/value.
