I think this really needs to be addressed. For example the php manual features a sample singleton implementation: http://www.php.net/manual/en/language.oop5.patterns.php Now how would one go about making it possible to extend the "Example" class without having to cut and paste the singleton() method to this extended class (one would probably also need to the instance property to hold an array of instances keyed be the class name)? Not exactly in the spirit of OOP imho. It seems to me the best solution to retain this "speed optimization" of resolving these things at compile time is to copy the implementations of static items over to classes that extend that class before this evaluation is done. Just a thought from an outside perspective, dunno if this is feasible however in the ZE2 implementation. Previous Comments: ------------------------------------------------------------------------ [2005-04-11 23:14:42] aknaub at 3st dot de Sorry, but this quote is nonsense. Every real OOP language (Ruby, ObjC etc.) resolves static methods at runtime. ------------------------------------------------------------------------ [2005-04-11 13:50:15] jbs at fromru dot com I've noticed some similar reports. For example, the one at http://bugs.php.net/bug.php?id=30235. Here is a quote: > > Sorry, you have a complete wrong idea og OO programming. > > Static methods are bound/resolved at compile time. > That is the compiler can replace self with the current > class. > So, it appears as it is a limitation of the compiler and the entire object model. I think such behavior makes inheritance of static methods useless because even if a static method is inherited, it still functions as in the class where it was declared. Moreover, inherited static methods are using the static properties which were declared in the parent class but not the inherited one. So, in my opinion "self" keyword should be replaced with the name of the inherited class during compiling. Or at least a new magic keyword should be added and named like "this", for example. ------------------------------------------------------------------------ [2005-03-30 23:47:28] [EMAIL PROTECTED] Andi, is this a bug or not? ------------------------------------------------------------------------ [2005-03-29 09:10:20] aknaub at 3st dot de I reproduced the bug with snapshot php5-200503282030, compiled as cli on Mac OS X 10.3.8. ------------------------------------------------------------------------ [2005-03-27 01:18:39] mongole at tuivelsminne dot at I reproduced the bug with snapshot php5-200503262330, compiled as mod_php in apache-1.3.33 on FC 3. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
