Referencing a static class from within another class

Question

I have a class:

class Site { public static $url; }

I assign a value to it: Site::$url = "whatever";

I have another class:

class Something { public function __Construct() { echo Site::$url; // does not seem to have scope? } }

How do I give scope to the Something class.

If they're in the same file, that should work correctly. I've just copied your code and it seem to be working fine, cannot recreate. Just double check you're doing Site::$url = "whatever"; before calling new Something(); — ninty9notout

It should work as you've written it above:

class Site { public static $url; } class Something { public function __construct() { echo Site::$url; } } Site::$url = 'whatever'; new Something(); // prints 'whatever'

If that's not working, it's likely because the classes are being declared in two different namespaces.

Just to add to this, if you are using separate files, you may want to ensure you are using require as opposed to include. This way missing scripts are flagged up sooner. Also having a good autoloader function is a must, just to cover your back ;)
