Previous Comments: ------------------------------------------------------------------------ [2019-08-21 09:47:38] 6562680 at gmail dot com Description: ------------ When i want to write facade for function that works by reference i should fully copy function signature into facade, otherwise when unpacking facade loses all references or something. It means i cant decorate or make facade with arguments unpacking, because i'll lost all references on these bridge. Test script: --------------- // declare function append(array &$ref) { $ref[] = 1; } Class Lib { public static function __callStatic($method, $arguments) { // just ignore $method for example... return append(...$arguments); // could be call_user_func('append', ...$arguments); // could be call_user_func_array('append', $arguments); // even could be call_user_func([ SomeOtherClass::class, 'append' ], ...$arguments); } } // run $arr = [1]; append($arr); var_dump($arr); // [1,1] // OK! Lib::neverMind($arr); var_dump($arr); // [1,1] // WTF? It should unpack args by references and then copy-on-write! Seems copy-on-write triggered on unpacking Expected result: ---------------- Saving references when passing arguments to child function Take care about magic __call, __callStatic and so on where we have 2nd parameter with arguments (possible packing) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78433&edit=1
