PHP software

I picked up a book on PHP that seems pretty good as a learning book and reference material.

Problem is, they don't state the software you need to test your code!!

I've got Tomcat on my system as a webserver, but what else do I need to be able to run and test my PHP code?

Note: The book goes into depth into XML technologies: SAX, DOM, XPath, and XSLT. Software to run these scripts would be nice too.

(a web page tutorial for intro to PHP and setting up your system to use it would be great, first and foremost)

That's an interesting link. Notice though, that what I said wasn't absolutely false. I had noticed it was a little slower in some cases, but the difference, as you can see, is rarely above 5%.

As for memory, that link shows it almost always takes a little more memory too - never more than 2.5%, but there are a couple cases where Perl takes up to 15% more memory, which is IMO more important as they seem to fall in the "considerably" more, not "about as much". Then again, this is probably up to the way the algorithms are implemented.

Also, keep in mind these tests are fairly generic and not too webapp-oriented. PHP code would probably be a little shorter than Perl's for more typical web application tasks.
