When I installed Symfony2 sandbox and try to check requirements by check.php I had 2 problems. My server don't have posix and intl extensions. I'm using WampServer 2.1e (32 bits) on Windows 7 32bit so my versions of apache and php are: Apache 2.2.17 VC6 ThreadSafe Php 5.3.5
I was trying to apply intl extension from http://windows.php.net/downloads/releases/php-5.3.5-Win32-VC6-x86.zip but i have weird error in apache log: "Can't find extension in c:/wamp/..." I'm sure that extension is in correct directory and enabled in php.ini.
With posix extension I have bigger problem. I can't find it at all on windows platform. In documentation of php it is said that it should be enabled by default, but it isn't.
