Somebody asked for some links to get started with PHP. Of course I lead them to the PHP.net official site, where the documentation is some of the best I’ve seen for any product.
I also suggested PHPDeveloper.org and PHPFreaks.com, though the truth is I usually Google any questions I have that the official docs don’t answer. Still, I’ve found some good info at both of those.
Finally, the PHP Cheat Sheet at ILoveJackDaniels.com is pretty nice to have around (cheat sheets mentioned previously).
