There are many options for displaying a popup but it requires HTML / CSS / JavaScript/ jQuery skills - not PHP. PHP is the server side scripting tool that produces the resulting HTML and JS that renders in the browser.

Bootstrap has a modal popup (if you are using Bootstrap)
http://getbootstrap.com/javascript/#modals

Failing that you have JQueryUI
http://jqueryui.com/dialog/

FancyBox
http://fancybox.net/

All of them will do what you need - all have good examples out there of how to implement a popup.

Bootstrap Modal will appear by default centered.

button code:
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
