Reference to static method in PHP?

Question

In PHP, I am able to use a normal function as a variable without problem, but I haven\'t figured out how to use a static method. Am I just missing the right syntax, or is this

Answer 1

PHP handles callbacks as strings, not function pointers. The reason your first test works is because the PHP interpreter assumes foo1 as a string. If you have E_NOTICE level error enabled, you should see proof of that.

"Use of undefined constant foo1 - assumed 'foo1'"

You can't call static methods this way, unfortunately. The scope (class) is relevant so you need to use call_user_func instead.

UseReferences();
