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)

Parenthesis cannot be ommited in some cases for function calls. Regex not built into the language's syntax. Array and hashes share the same, simple syntax. Brackets aren't mandatory, and no postfix if/while/etc. hack. All variables start with $ regardless of what they are. Etc.....
