Thanks Coug. Funny you should mention that one, it was one of the other two that I decided not to get in favour of this one. Reasons? In rough order of importance:
* I need to know PHP and MySQL (and doubtless the tricky bits of interfacing one to the other, which are more likely to be covered in a book about both than in two books, one about one and the other about the other).
* The PHP 5 thing put me off. PHP 5 is still in test status, and it's PHP 4 I'm working with. PHP 5 knowledge can come another day when I'm actually running it.
* I flicked through all three and all seemed to have the sort of stuff I need, but this, although the biggest and the heaviest by far, seemed at least as readable (looking at a few random pages) as the others.
* This one, although published by an American company, was actually written by two Australians - Victorians, no less! - and that seemed a better thing for this Australian to be buying. (In fact, they are on the staff at the same university where my sister teaches - not that that is likely to get me any special extra tuition!)
Why not some other one completely, such as Doug's Begining PHP4? Because these were the three I could lay my hands on today, without driving to Melbourme or waiting for a mail order.
So far, I am very happy with PHP and MySQL Web Development.
Mostly tonight, though, I have been learning how to set up a second wiki for testing purposes. All trial and error stuff, but I got it eventually, after a massive battle with SQL not letting me have root access. I now have MediaWiki 1.2.4 still happy as the main install, and 1.3 beta 2 on test.
For my next trick, I have to figure out how to back up and restore MySQL databases, and in particular, how to restore an existing 1.2.4 database to a new 1.3.x install.
But not tonight!
