You might have to perform a str_replace, replacing all instances of "http://www.someblockedsite.com" with your proxy script set to point the blocked domain.

Of course you'll also need to change

Code:

$url = 'http://www.someblockedsite.com';

to

Code:

$url = $_GET['url']

so that you can allow for other sites.
