Static properties in PHP

Question

When are static properties initialized, as I know other member properties are initialized when object is created.

Thanks

Answer 1

Declaring class properties or methods as static makes them accessible without needing an instantiation of the class. A property declared as static can not be accessed with an instantiated class object (though a static method can).

So, they are available after they have been declared.

Answer 2

Static properties? Do you mean static variables or methods?

Either way, they are initialized when the script is parsed, or the class is defined.
