It's close enough to the same thing that it has the same problems. As far as I am aware, a static variable in a function is stored in global memory as a singleton. It's logically the same as a global variable, but with access restricted to one function. A static property of a class is also stored in global memory. It's logically the same as a global variable, but with a funny name that has colons in it. It may be access restricted depending on the code. (Engine experts, if I am subtly wrong there please do correct me.) So static variables and static properties are both simply "globals with funny extras." And global-maintained state is well known and understood as a bad idea that hinders testing, refactoring, tractability, maintenance, and everything else developers care about. Using global state, with or without funny syntax around it, is the anti-pattern we should not be encouraging. Generally speaking, even my prototypes eschew globals and statics in 95% of cases. --Larry Garfield -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
