PHP5 treats the left part of such assignment as an independent local variable, while HHVM treats it as a reference to the method parameter. This leads to the value of the parameter being changed, which, in turn, causes func_get_args() to return not what is expected. This commit is a part of the effort to make Symfony run flawlessly on HHVM. This issue causes a bunch of Symfony tests to fail on HHVM.
Doctrine 2 ORM
Doctrine 2 is an object-relational mapper (ORM) for PHP 5.3.2+ that provides transparent persistence for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication.
