Display PHP variable from a different page

Question

I have this code:

<div style="width:100%; position:fixed; z-index:999; top:0; left:0; padding:10px; background-color:#666666; height:50px;">
<h3><button id="inbox_button" >Inbox <?php echo $messages_num; ?></button></h3>
<div id="inbox_div" style="background-color:#eeeeee; width:350px; height:400px; overflow-y:scroll; display:none; margin-top:20px; padding:0px;">
<?php require_once $_SERVER['DOCUMENT_ROOT'].'/admin/includes/menu_messages.php'; ?>
</div>
</div>

i am using require_once to include a php file. the file (menu_messages.php) has the PHP variable $messages_num; in, how can i echo this on the Inbox button - i have echoed it above but its not displaying

You're echoing it before including the file that contains it? — Damien Pirsy

You can not use a variable before it is declared, this is very simple and basic, you should learn php — user924016

but if i declare the require before i echo the variable, it will show my required file in the wrong place — user2135867

@charliejsford that makes no sense. Read some basic tutorials — user924016

you need to include the other php file before you can call any variables stored within it.

You should require the file first, the output is blank because the file holding the variable isn't loaded yet.
