When you including like include 'http://www.classexample.com/myfirstclass.php', you do not include any files.
If you really want to use a PHP code from other domain, rename your class definition file to myfirstclass.txt
But the whole idea of cross-domain class definition seems very unusual, not to say more.
If both sites share the same server, do include files, not URLs
