Is there a book on regex good enough to recommend?

Glad to know there are several choices like XAMPP, WAMP, EasyPHP, Reactor, etc. Questions: (1) If one wishes to avoid the need to "upgrade" to a more powerful installation later, which one(s) should one install under WinXP Pro? (2) How secure are each of the installations? What's the chance of hackers hacking into the computer via the installation? In terms of being hacker-proof, which of the installations is the most secure, and which is the least secure? Which one has the best default security? (3) What are the key caveats to follow to prevent hacking as a result of installing such a PHP programming environment? Thanks to all for any input. I am sure many beginners will appreciate knowing the answers to all the above questions.
