OpenSSL and IIS
uncomment the following:
Make sure you have config the following section pointing to your php install directory (in my case is located in a second partition at e:\php) (very recommended practice)
; Directory in which the loadable extensions (modules) reside.
extension_dir = "e:/php/ext"
Add your php directory to the PATH variable
on windows console type:
(remember replace e:\php with YOUR directory)
(note that using %path% is the same as var+=value, so the directory will be appended at the end of the variable)
php5 come with all the dll in the zip package so if you add the php directory to the path variable, you don't need to move anything to your windows system directory (very safe for later updates, because you just replace the content of your php directory)
After all these step you ready.. but of course you need to restart your IIS to apply changes, so
right click on your computer
all task>restart IIS
