You most probably don't want to include URLs into your main php file, but the local .php-files. include ('/path/to/a.php'); instead of include ('http://url/to/a.php');

(source: http://php.net/manual/en/function.include.php)

You probably need modify php.ini allow_url_include = On.

But better never include files via http.

You should never include files via an absolut URL, because you will not be including the actual code, but the result of it. Instead use relative paths or server paths (/home/user/public_html) Easiest way would be via relative paths. For example, if you have index.php and header.php in the same folder, you can just use: include('header.php'); If the files, are in another folder, for example you have header.php in an 'includes' folder, than you would use in your index.php: include('includes/header.php');
