On most of php servers configuration directive allow_url_fopen
(http://php.net/manual/en/ref.filesystem.php#ini.allow-url-fopen) is set to
off, so you cannot parse remote script to that server. Sometimes it is not,
and there is some possibility of doing the above, of course, only when some
coder have not done his job properly.

Solution to "the problem":
Use your brain while coding, and test your code.

Quick and usefull solution:

include(preg_replace("|[^\w\.]|", "", $page));
