Passing variables on the URL

[system]

Can anyone tell me why this isn’t working? I’m in an intro PHP course and this is the example our professor gave us, so I’m not sure what I could possibly be doing wrong.

He gave us this html file:

Preferred Greeting Do you prefer a formal greeting or an informal greeting?

• Formal
• Informal
• Friendly

And this PHP file:

<?php $greeting=$_GET['greet']; ?> <?=$greeting ?> World! <?php echo "greeting World!"; ?>

But when I open it and click the links in my browser, it shows the php code, not the actual greeting.

Thanks!

A php file can’t be opened, it has to be run thru a server. The professor didn’t explain how to set up your environment?
