Dan’s Online Diary

When PHP was first developed, it was an acronym for Personal Home Page tools. But it got rehashed and extensified, and the new developers of PHP thought that the term 'personal' was too restrictive. So PHP now stands for PHP: Hypertext Preprocessor.
Another shining example of a recursive acronym is GNU, which is an acronym for GNU's Not Unix.

So, in light of all this, I have decided to change my name from Dan, to the acronym Dan, which stands for Dan's Acronymic Name.
