PHP doesn't have this luxury - people can call files whatever they
like. However, PHP5 does have a nice feature to deal with this. In
your class1 class, create a function called __autoload like this:

function __autoload($class_name) {
require_once $class_name . '.php';
}

In this case when you ask for a new class2 and you've not required it
before, it will automatically call __autoload with $class_name set to
'Class2', which then requires the class file according to the pattern
used in the function, in this case 'Class2.php'. Note that while PHP
is not case sensitive to class names, the file system you're on
probably is, so keep your case consistent throughout.
