This issue has already been fixed in the latest released version of PHP, which you can download at http://www.php.net/downloads.php PHP 5.5 added this (see RFC: https://wiki.php.net/rfc/class_name_scalars) You can do ClassName::class to get its fully-qualified name.

When using class name as hardcoded string this isn't possible. Also in PHP 5.3 possible workaround for this missing feature is to create method "static function __CLASS__() {return get_called_class();}" in all base classes which is extended by other classes. Sure it doesn't help for the interfaces. ------------------------------------------------------------------------ [2011-03-29 17:32:08] webseiten dot designer at googlemail dot com Description: ------------ Please add a way to get the fully qualified class or interface name without the need to create an object. While it is possible to declare a static variable in classes as a workaround, this will not work with interfaces, as you can't declare members inside them. A common trick I've seen is to use a constant: namespace Foo\Bar; interface A { const __NAME = __CLASS__; } factory(Bar\A::__NAME); // calls factory with '\Foo\Bar\A' Though this won't work with inheritance. The magic __NAMESPACE__ constant is also no help when importing namespaces. I propose to use the __CLASS__ keyword to implement such a feature, as it is not allowed to have a class constant of this name: namespace Foo\Bar { interface A {} } namespace Orange\Banana { use Foo\Bar; echo Bar\A::__CLASS__; // should print "Foo\Bar\A" } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54417&edit=1
