PHP Phrasebook Competition, Once Again

That was quick; after a mere 20 minutes, both copies were gone. One went to Chris Shiflett, who invented a new principle: "security by clarity". By posting the correct answer as a comment, he obviously wanted to secure that no-one else dared to enter the competition. Several other people were brave enough however, Sam Stevens being the quickest of them.
The correct answer, of course, was Zak Greant who will co-author the upcoming MySQL Phrasebook. The doppelganger trivia was inspired by this blog entry and is documented here.
Now some people have complained that the question was too hard (or too easy for insiders). Well, I have one more copy of the Phrasebook to spare, so the first person who mails me at wenz at php dot net what the acronym PHP stands for nowadays gets the copy. I know, the question is lame, but some books still don't get this right. The same rules as with the previous competition apply.
Update: Took a little longer this time, probably the question was too hard The book is gone!

Update^2: The books are in the mail; the postage actually exceeds the cover price ... sigh
The happy winners are Thanatip Sriviroonchai and Aaron Wormus. (Aaron came in second, but only a few seconds after Thanatip, so I decided to add one more copy to the lot.) The correct answer was of course PHP: Hypertext Preprocessor, just have a look at the title bar of the PHP homepage. Some websites and articles and books claim "Hypertext Preprocessor" or "PHP Hypertext Preprocessor", but this is obviously wrong. Congratulations to the winners!
