The PHP chapter from Apache Security available for download

I have made the PHP chapter from Apache Security available for free download. When we made the decision to set the installation and configuration chapter free, several months ago, I did not realise this chapter only told one half of the story. Most people need to configure Apache *and* PHP. This is now fixed, and the two chapters together make a valuable resource. My long-term plans are to convert both chapters to DocBook, keep them up-to-date, and publish them as PDF and as HTML. But not yet--the content is still very fresh!
