get_file_contents执行PHP部分

I am trying something like this:

$content = get_file_contents("abc.file");
echo $content;

The problem is that abc.file contains some HTML tags along with a php statement:

<?php require_once('a_php_file.php') ?>

How do I get the server to execute the php parts of abc.file before it being echo(ed).

Thanks!

Use include(): you might need to make some php configuration changes to let include work on remote files, but typically that's what you do.

Either that or eval(), I think.

Use include:

include 'abc.file';
