PHP 'global variable'
<p>I am creating a game in PHP, and am having a problem with global variables. Depending on which button is pressed in my HTML page, a corresponding PHP script is run and a function is called depening on the <code>isset</code> function.</p>

<p>My question is this: I want to keep a score variable, and I would like to have access to this variable in the future after multiple <code>post</code> statements have been issued.</p>

<p>I have tried using the <code>global</code> keyword but this does not seem to do what I am expecting.</p>

<p>Can I please have some help with this?</p>
