I can understand that some people coming from C++, Java may be shocked by the behavior of a static variable in a static function. And the need to improve things.
Maybe can you add *virtual static* keywords as a replacement for old behavior in your RFC <https://wiki.php.net/rfc/static_variable_inheritance> . You would satisfy me. class A { static function Counter() { static $count = 0; virtual static $i = 1; return [++$count, $i++]; } } class B extends A {} var_dump(A::Counter()); // array(int(1), int(1)) var_dump(A::Counter()); // array(int(2), int(2)) var_dump(B::Counter()); // array(int(3), int(1)) var_dump(B::Counter()); // array(int(4), int(2)) A::Counter::$count = 665; // Great Feature A::Counter::$i = 0; //Initialize B::Counter::$i = 0; //Reset In C Poo we could get : /*header*/ typedef struct _A {// Instance class A } A; typedef struct _AClass {// vtable class A int counter_i;// php: virtual static $i void (*counter)(void);// php: public static function counter(){} } AClass; typedef struct _B {// Instance class B A parent_instance; } B; typedef struct _BClass {// vtable class B AClass parent_class;// B contains its own virtual static variable $i } BClass; /*source*/ int A_counter_count = 0;// What did you expect ? //... A_counter_count = 665;// php: A::Counter::$count=665; A_class_entity.i = 0;// php: A::Counter::$i=0; B_class_entity.i = 0;// php: B::Counter::$i=0; Best regards, Serge Le mar. 23 févr. 2021 à 15:02, Nikita Popov <nikita....@gmail.com> a écrit : > Hi internals, > > While looking into various issues related to static variable handling, I've > become increasingly convinced that our handling of static variables in > inherited methods is outright buggy.
