那么如何在PHP中创建一个全局类名?

I have a class called "user" with a function "createAccount". Within it I like to access another class via PostageApp::mail

But as this class is outside the scope it is not accessible. global seams to work for variables only. So how do I make a class name global?

include_once('../../ext_scripts/postageapp_class.inc');

class user {
  function createAccount(...) {
    global PostageApp;

    [...]

    $result = PostageApp::mail($mailTo, '', 'verify_email', array());
  }
}

    If you are absolutely sure that the class has been defined in an included file, there is only one thing affecting its visibility in another file: I suppose the PostageApp class is in another namespace, as this is the only reason another class could have a different scope in PHP.

    The keyword global is only necessary for global variables. Functions and classes are always accessible in any scope as soon as they have been declared.
