Well, right on the heels of the latest PHP release comes PHP 4.1.0 RC1. This one's the precursor to the next big release of PHP with tons of new goodies for us all to play with. So, if you're feeling daring and want to mess with bleeding edge stuff, get PHP 4.1.0 RC1.
I also found a few tutorial links for you this morning - the first one is a sessions intro and background. It gives you a good jumping off point for working with sessions in PHP, and gives you some good sample code for it. Also, on the same site, there's another tutorial about something that several people overlook - error handling in PHP. They show the various kinds of erros that PHP can throw out as well as the ways that you can catch them. Apparently, you can even throw them over to a remote machine for logging!
Not to be outdone by the other sites posting tutorials, the NewbieNetwork has posted a link to a ZDNet tutorial on mail(). For those that haven't used this handly little function, it can be great for just about anything - even reporting errors directly to you (without all that messy user intervention). That's my latest use for it - having the script email me with the problem it hits.
