I don't get why do you say it's not a bug? Consider my reproduce code. why do the first and second property accessors work and the third (final) one does not? as i understand the final statement ($a->a->a = "";) should do: $a->__get("a")->__set("a", ""); so what's wrong with that? no recursive __get or __set, everything should work by specification... or am i wrong? if so, where? Reproduce code: --------------- <?php class A { function __get($name) { return new A(); } function __set($name, $value) { } } $a= new A(); $a->a->a; // only __get = ok $a->a = ""; // only __set = ok $a->a->a = ""; // __get and __set = error ?> Expected result: ---------------- the code should work ok. Actual result: -------------- Fatal error: Cannot access undefined property for object with overloaded property access in test.php on line 15 this error only happens if php would need to call __get and __set of some classes (sequentially not recursively) to resolve one (lhs) expression. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32913&edit=1
