How to use PHP/jQuery to realize a unique user on load?
<p>I have a webpage that stores the user ID of someone who clicks a button on the page.  Once the button is clicked, that user needs to be able to see content (just another button) that only that user can see. Other users on that page won't be able to see that button.</p>

<p>The problem I'm having is I don't know how to use that unique user ID, which is superglobal,  to recognize on load what the user ID is, and how to execute if its the correct user, show the otherwise hidden inputs.</p>
