I have used the web platform installer (version 4.6) and successfully installed (according to it) "PHP 5.4.14 for IIS Express". Yet when I open IIS and click on any of my sites the PHP module doesn't show up in the "Features view" as you can see below.
Any ideas?
Thanks.
UPDATE:
Turns out I hadn't installed the PHP manager extension, which is what I saw looking for. Thanks anyway.
