Thank you for taking the time to write to me, but if this is not a bug then this is a bad design of the method. I've double-checked the documentation available at http://php.net/manual/en/reflectionclass.newinstanceargs.php which said 'This function is currently not documented; only its argument list is available.' and said nothing about the numbers of the element in the given array. If you want to make a factory function with vararg, then you don't want to case about the number of the parameters. I think this should work: function factory($className /* and other params here... */ ) { $rc = new ReflectionClass($className); $params = func_get_args(); array_shift($params); return $rc->newInstanceArgs($param); } The new $className(...) construction doesn't work here. What is the difference between class A {} and class A { function __construct(){} } from the view of the construction? Both can be constructed by a zero-arg constructor call, new A(). If I've an array containing zero elements, why should not the $rc->newInstanceArgs($array) works in the first case, even it does in the second?

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Do not pass any param to method. Just use $rc->newInstanceArgs(); ------------------------------------------------------------------------ [2009-08-26 16:12:00] sebcsaba at freemail dot hu Description: ------------ I've got a class without a constructor, and I want to instantiate it by ReflectionClass::newInstanceArgs with an empty array as arguments. This causes: ReflectionException: 'Class A does not have a constructor, so you cannot pass any constructor arguments'. If I define an empty default constructor, this works well. Reproduce code: --------------- class A {} $rc = new ReflectionClass('A'); $a = $rc->newInstanceArgs(array()); Expected result: ---------------- Create a new instance of class A, using default constructor behaviour. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49376&edit=1
