What php code would I used to display code inside another php file.

Like for example:

Say I have a php file at: http://www.myhost.com/myfolder/test.php

And I want to have a seprate php page to display the php code in that file on the screen. How would I do this?

I thought this may work but I'm not sure.

code:

---

<?php
echo http://www.myhost.com/myfolder/test.php
?>
