after hours to read docs about Wordpress I don't find how to get a code everywhere in my page (thew module, snippet or other).

In functions.php

<?php 
function foo_global() {
global $var;
$var = "foo";
}

add_action( 'wp_head', 'foo_global' );

I want to access in different par of my page to $var (especially blocks).

I try thru xyz PHP Code module ou Code Snippets module, but that display nothing.

I don't understand where I'm wrong so anyhelp is welcome.

One of the common ways: enable session (in functions.php) in WP, then use session variables. For reference, see this [SO_link](https://stackoverflow.com/questions/23811748/how-do-you-use-session-variables-in-wordpress) – Ken Lee Mar 20 '22 at 13:51
I thought it's a little bit dirty and I don't need that all the pages, but it works. Thanks – Richard P. Mar 20 '22 at 17:51
Another way which doesn't persist the value when you change page is `$_GLOBALS`. – Andrea Olivato Mar 21 '22 at 01:53
Yes it's far better in ly opinion – Richard P. Mar 21 '22 at 19:54
