Loading HTML or PHP files into Popup

Looking for a responsive Modal Popup plugin that will load and execute a PHP file and HTML files. Currently using Javascript popup, but it opens in new window and is not responsive. I need one that is Modal and overlays. I pass parameters to the PHP file to dynamically change the content depending on which product they are in. Will the new version be able to load PHP?

If not, does anyone know a solution?

Here is a call to my javascript Openpopup function currently….
Would like to do the same type of call with a Modal popup. I am passing the variables for Product Number, and Title.

<a href="openpopup('www.mysite.com/php/ShowReviews.php?Productnum=XXXXXX&MODEL=Product%20Name')">Click for Reviews</a>
