The current [YAML 1.2] specification clearly states: > JSON's RFC4627 requires that mappings keys merely “SHOULD” be unique, while YAML insists they “MUST” be. The outdated [YAML 1.1] spec contained a crystal clear note on how the error of duplicate keys is to be handled by parsers, which is (sadly) no longer contained in the latest 1.2 spec (only leaving the requirement): > It is an error for two equal keys to appear in the same mapping node. In such a case the YAML processor may continue, ignoring the second `key: value` pair and issuing an appropriate warning. This strategy preserves a consistent information model for one-pass and random access applications.

README
What is Symfony2?
Symfony2 is a PHP 5.3 full-stack web framework. It is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP.
Symfony can be used to develop all kind of websites, from your personal blog to high traffic ones like Dailymotion or Yahoo! Answers.
Requirements
Symfony2 is only supported on PHP 5.3.3 and up.
Be warned that PHP versions before 5.3.8 are known to be buggy and might not work for you:
-
before PHP 5.3.4, if you get "Notice: Trying to get property of non-object", you've hit a known PHP bug (see https://bugs.php.net/bug.php?id=52083 and https://bugs.php.net/bug.php?id=50027);
-
before PHP 5.3.8, if you get an error involving annotations, you've hit a known PHP bug (see https://bugs.php.net/bug.php?id=55156).
-
PHP 5.3.16 has a major bug in the Reflection subsystem and is not suitable to run Symfony2 (https://bugs.php.net/bug.php?id=62715)
Installation
The best way to install Symfony2 is to download the Symfony Standard Edition available at http://symfony.com/download.
