Well I am under the impression that in the definition static $var=<value>; <value> should be assigned to $var only the first call...so what I want to do is to use that for implementing a singleton, like that: class Class { //... function &getSingleton() { static $instance=new Class(); return $instance; } // ... } (similar to Class& getSingleton() { static Class instance; return instance; } in C++, and yeah, I know that that ain't thread safe;) Anything wrong with that?
