Making Variable out of include file

[doublewam]

What would be the proper way to do the following...

$msg = include("dfp/includes/email_receipt.php");

Basically, I need it to make all of the HTML on an extarnal page become the contents of a variable. What is the correct syntax for this?

Thanks in advance.

do
$msg = file_get_contents("dfp/includes/email_receipt.php");
