Congrats to Brian DeShong for having his submissions from this year's TestFest be included in the next release of PHP, version 5.3's build.
Someday I'll look back on this post and think it's super lame, but my recent submission of two tests for PHP's putenv() function made it into PHP_5_3! I've officially made a contribution it's a red letter day, folks. Without Atlanta PHP and PHP's Testfest, none of this would have been possible.
His tests ran with putenv() and the safe_mode_allowed_env_vars/safe_mode_protected_env_vars settings in use. You can see the inclusion in this commit message (by Lars Strojny).
