PHP Version to use for Facebook SDK 3.1.1

What is the best version of PHP to run for Facebook SDK 3.1.1? I am currently running PHP 5.2.6, but was wondering if 5.3.8 is better? Is there any thing wrong running eit开发者_StackOverflow社区her/or?

You will need PHP5.2+ to use the Facebook SDK. I tried looking in their documentation for system requirements, but Facebook's docs aren't brilliant.

Using a more recent version of PHP is completely up to you and your application, as it won't give you any noticeable benefits.
