Req #44604 [Opn]: newInstanceArgs (ReflectionClass) and visibility

Edit report at https://bugs.php.net/bug.php?id=44604&edit=1 ID: 44604 Updated by: requinix@php.net Reported by: vituko at gmail dot com Summary: newInstanceArgs (ReflectionClass) and visibility Status: Open Type: Feature/Change Request Package: Reflection related Operating System: Debian GNU/Linux PHP Version: 5.3CVS-2008-04-02 (CVS) Block user comment: N Private report: N New Comment: As of PHP 5.4 you can use ReflectionClass::newInstanceWithoutConstructor() and manually invoke the constructor. $rc = new ReflectionClass("foo"); $obj = $rc->newInstanceWithoutConstructor(); $ctor = $rc->getConstructor(); if ($ctor) { // constructors are optional! $ctor->setAccessible(true); $ctor->invoke($obj); } A couple more function calls seems a small price to pay for the ability to do something the class itself specifically tried to prohibit you from doing. Previous Comments: ------------------------------------------------------------------------ [2013-11-20 10:39:51] jerome at taotesting dot com I would also argue that such a feature would be absolutely great for Unit Testing. If method calls can be done on protected/private methods via ReflectionMethod::setAccessible(), why not allow that with private constructors? All the best, Jérôme ------------------------------------------------------------------------ [2008-04-04 18:00:44] jani@php.net Reclassified. NOTE: Discussion about this should be done on the internals mailing list.. ------------------------------------------------------------------------ [2008-04-04 14:06:57] vituko at gmail dot com I didn't say it was a bug. I only said that it is a limitation... maybe easy to change. ReflectionClass -> newInstanceArgs is very nice but only works with public constructors. If a class constructor is private, for example, you cannot instantiate it with this method, even from this class scope. The same example with call_user_func_array, you change the constructor with another method and it works... But this function doesn't allow to instantiate an object (you can only call a parent constructor on an already instantiated object). So, in this context (a class with a private/protected constructor), the only way of instantiating it with an arbitrary number of arguments is to build a string and use eval... not very nice nor performant.

Constructor must be public anyway. So ... eval is not so bad. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=44604&edit=1
