Professional PHP4
PHP is an open source server-side HTML-embedded web scripting language for creating dynamic web pages. Outside of it being browser-independent, PHP offers a simple and universal cross-platform solution for e-commerce, complex web, and database-driven applications. Professional PHP4 will show you exactly how to create state-of-the-art web applications that scale well, utilize databases optimally, and connect to a backend network using a multi-tiered approach.
Almost an year since its release, this book has stood the test of time, and proved to be what it promised -- an up-to-date, advanced book on PHP -- a category in which there are very few worthwhile entries to date.
It provides a solid, fast-paced drill on the rudimentaries of PHP (although the fast-paced installation instructions come in the form of classic compendia -- worth 100 pages) for seasoned programmers, before it plunges head straight into the more advanced areas of the language. Each chapter reads a bit like a tutorial on a particular area of advanced PHP development.
If you are a competent programmer in just about any other language or have grappled with HTML before, then this book will teach you PHP from scratch . It will also introduce you to many of the more advanced areas of PHP programming, and is a treasure trove for information on diverse tasks possible with the language.
Notable topics include:
- Object Oriented Programming
- Sessions and Cookies
- Coding an FTP Client
- Sending and Receiving Email and News
- Networking and TCP/IP
- Non-Web Programming (including GTK)
- PHP and XML
- PHP and MySQL/PostgreSQL/ODBC
- Security
- Multi-tier development
- Optimisation
The code for the examples presented in the book is available for download, from the publisher's web site.
Although this book is reasonably complete, it lacks sufficient depth for experienced PHP developers who want to wade into the depths of specific PHP related tasks. Having said that, the publisher has provided information (of course at a separate cost) on specific areas with their second level PHP titles -- Professional PHP4 XML , Beginning PHP4 Multimedia Programming , Beginning PHP4 Databases and Professional PHP Web Services .
Suffice to say that the book has packed together a lot of diverse information (in 975 pages).

I would put the google HTML version of it, but it seems to be buggered.
I've said it before, and I'll say it again... the PHP website should be enough for anyone with basic programming skills. It's simple, clearly explained, and there's many examples and fixes posted by people. The only thing that would be helpful would be a PHP Cookbook that's as good as the Perl one.

I've been using php for about 5 years professionally and have actually been looking into using Java, mostly because I'm interested in the concepts behind MVC design.
But one of the things php has given me over the last 5 years is total rock solid stability. I mean, I've hacked up some complete crap code over the years but I've never once had a php related crash(and apache only ever crashed when we tried integrating Cold Fusion into it).
In testing Java servlets I have gotten out of memory errors in a database app I've written, but that could very well have been a lack of knowledge on my part(maybe I had the server misconfigged). I'm reading up more on admining/designing for Java now and will do more serious tests in the future.
But don't dismiss php as a toy language. The code you create can be messy, but it's rock solid stable. 5 years of 80k+ lines of code without any crashes is nothing to laugh at.
I was going to pick up this book, based on the recommondation of friends (programmers) and online reviews, but when I thumbed through it in the bookstore, it just seemed...weak. Thin.
This is PROFESSIONAL PHP programming, not BEGINNING PHP. Why even have the 100 or so odd pages on installation? This book is not targetted at newbies, it is for the serious developer. OK -- you're a J2EE dude who want to check it out; doesn't have PHP installed. Lots of references on the Web, and if you can't find them...you're not a Web developer.
While the book probably would be helpful as a reference in some cases, I was just disappointed in it. The cookie/session section was a joke (and this is new in v4, so should be fairly rigorous).
I didn't buy the book. And I like having references around. I have 7-8 open on my desk right now, from Perl through DHTML to PHP. Oh well, as people have noted, v5 is coming, so I guess we shouldn't get our packets in a bunch...
The 'id=foo&name=bar' translating to $id and $name defined is per the 'register globals' setting, which is now off by default in new installations. You'd need to identify where things are coming from:
$_GET['id'];
More typing, but generally safer, as it does force you to think about where things are coming from.

I can weigh in on that a little, having first learned and worked with ASP for 2 years before I got in to PHP, and having now been active in ASP and PHP both for that past two years.
ASP vs PHP there is so completely no comparison. There is only one single thing that ASP does that is easier than in PHP, and that is application-scoped variables with out a database. I've written my own PHP classes to facilitate this, and although they may not be as efficient as ASP's memory resident access, they are just as useful.
The hugely wide variety of functions PHP provides make programming a delight where you work more on your programming concepts and code flow than on authoring code. There are simply hundreds of functions available in PHP that I use on almost every page, that would require custom-written functions (that thus run as script, at lower performance than the precompiled PHP functions) that are simply not available in ASP. Try to do a join() or split() in ASP. Yes, it's doable, but with quite a lot of legwork. How about regular expressions? Searching, replacing, replacing with code execution, and more? Not gonna happen in ASP, nope.
Then there are SIMPLE things that are HTTP standards that are simply lacking in ASP. For example, uploading a file. Gotta buy a plugin in ASP to do that. Or uploading creating an array of elements on a form. If you want to have an unknown number of entries in a form, in PHP, you can name the input fields, "field[0]","field[1]","field[2]" and they come in as an array. Or you can even name them "field[]","field[]","field[]", and they will come in as an automatically indexed array. Useful when you want to do things like add rows of input to a table with javascript, and have a script that easily handles the collection. Try to upload an array in ASP, and you have to write code that breaks down the field names to your liking.
There are so many functions that I take for granted in PHP that I now have my own library of PHP functions rewritten in ASP so that when I am authoring in ASP, I'm not as limited by the language. Just try to do an md5 in ASP, or any other cryptographic operation though, I dare you.
Ok, sorry, rant over, been working on an ASP for the past month solid, and I think I'm going through PHP withdrawl.
