Question

I’m trying to store an array in a PHP GLOBAL like so:

// file_1.php

include 'functions/session_metrics.php';

$project_data = array();
$session_data = array();

if (isset($_GET["product"])) {

    $product = explode("|", $_GET["product"]);

    foreach ($product as $id) {
            list($project, $sessions) = getProductInfo( $id );
            $project_data[$id] = $project;
            $session_data[$id] = $sessions;
    }

    $GLOBALS['project_data'] = $project_data;
    $GLOBALS['session_data'] = $session_data;

}

Now from another file I’m trying to retireve it like so:

// file_2.php

$data= $GLOBALS['project_data']; 
print_r($data);

But I see the error:

Undefined Index: project_data...

What am I missing?

Why not just use native php $_SESSION to store session data:

$_SESSION['that'] = 'this';

echo $_SESSION['that']; //echoes `this`

Also by doing this: $GLOBALS['session_data'] = $session_data; you are setting a value equal to itself (which is implicit) unless $session_data is inside of a function.
