I want to create a php multipage form, but i can't use $_SESSION variables to save and reuse data when i'm changing pages.

I've tought to use a personal global array (eg. GLOBAL $data; $data = array();) where i'll put my field variables, but when i go back through pages (eg. from pag 2 to pag 1), array $data is empty.

Where i've done wrong?

You can use variables by below ways:-

Global variables:-

$GLOBALS['variable'] = 'value';
// use them globally

Static variables:-

define('VARIABLE_NAME', 'value');
// static only. value is not changable

Session variables:-

session_start(); // need to define below line
$_SESSION['variable'] = 'value';

If you need to change variables value by page to page then you should use SESSION.

Check this link for GLOBAL variables.

you have to use keyword GLOBAL while accessing data. for example on 

page 1

$data = array("a", "b");

on page 2

global $data;
print_r($data);
