PHP Hacks
Michael J. Ross writes "Given the current popularity of the Web development language PHP, it makes sense that newcomers to the language have a large number of introductory and reference volumes from which to choose. But for the more advanced PHP programmer, there are far fewer titles that explain how to make the most of the language, by applying it to solve relatively substantial problems. One such book is PHP Hacks: Tips & Tools for Creating Dynamic Websites, by Jack D. Herrington. Read the rest of Michael's review.

summary
Practical techniques and source code for improving PHP-based Web sites and applications.
The book was published by O'Reilly Media in December of 2005. Despite its title, PHP Hacks: Tips & Tools for Creating Dynamic Websites is clearly intended to show how PHP's capabilities can be extended beyond its most common usage for creating dynamic and database-driven Web pages, and can be employed in such areas as graphics, reporting, Web site testing, code generation, and even fun purposes (for those few programmers who find the former topics less than entertaining). The author, assisted by six contributors listed in the Credits section, manages to pack an impressive number of general programming ideas and PHP-specific topics within this title's 468 pages. The material is grouped into 10 chapters, each of which contains a generous number of "hacks," each in its own section.
As with most if not all of the other titles published by O'Reilly, this book has a Web page that offers an overview of the book, its table of contents, all of the book's code (in both Zip and tar file format), and a list of confirmed and unconfirmed errata. In addition, the site hosts five sample hacks (in PDF format): accessing iPhoto pictures, generating Excel spreadsheets, avoiding the "double submit" problem, reading RSS feeds on your PSP, and creating custom Google Maps. Perusing these hacks would give the prospective buyer a clear sense as to the style of the book's other 95 hacks, as well as the (low) level of PHP expertise needed to understand them.
The book begins with a preface that describes the organization, conventions, and icons chosen for the book. Also, it covers the legality of the code samples, lists contact information, and mentions O'Reilly's Safari online book service, which contains this title among many other PHP resources. What is perhaps most unique about this book's preface is that the author identifies over half a dozen weaknesses commonly seen in PHP applications, and explains how his book addresses those problems. In addition, he makes explicit how some of the hacks can be used for jazzing up one's Web site or Web-based application.
The first chapter discusses how to install PHP on Windows, Mac OS X, and Linux, and then verify that the installation was done properly. Herrington then briefly explains how to install MySQL and perform some basic database management. The chapter concludes with coverage of installing the PEAR library on your local machine and on your Web host's server (which is incorrectly identified as your "ISP machine," apparently assuming that most developers choose their Internet service providers for hosting their sites, when in fact the opposite is true). Since the typical reader of a non-beginning book such as this no doubt has one or more introductory and/or reference PHP books at hand, it would seem superfluous to waste time and space explaining how to install these components. But few pages are taken up by the material.
The next chapter is devoted to hacks that help to jazz up the design of one's Web sites, including how to create a skinnable interface, build a breadcrumb trail, create HTML boxes, add tabs to your interface, and other valuable techniques. Subsequent chapters offer hacks in the areas of dynamic HTML (DHTML), graphics and digital pictures, databases and XML, application and e-commerce design, patterns and PHP object orientation, testing and documentation generation, and building alternative user interfaces. The 10th and final chapter covers some "fun stuff," such as creating dynamic playlists, developing a media upload/download center, and even putting Wikipedia on a Sony PlayStation Portable.
Rather than try to explain in detail all of the many topics covered in the book, I instead encourage the interested reader to visit the publisher's Web page, and scan through the table of contents provided, to get a better idea as to how much of the book would be of interest to the individual. Also, the five sample hacks listed on the site, would be well worth examining and trying out. Overall, the topics chosen reflect favorably upon the judgment of the lead author and the other contributors to the book. The typical PHP veteran would likely be interested in most of the applications covered, and would probably learn some new tricks, especially in the areas of patterns and code testing, regardless of their level of experience.
Like all books, this one is not perfect. As with the first printing of most technical books; particularly those chock-full of source code; the book contains a fair number of errata, likely even greater in number than those reported and listed on the publisher's Web site, as mentioned earlier. Consequently, any reader who chooses to test the sample code and he or she would be encouraged to do so; should keep one browser window or editor buffer open and devoted to those errata, so as to minimize the time spent trying to figure out why some sample code is not working as advertised.
Some readers posting in forums have complained that the sample code has evidently not been fully tested on all platforms, nor in all Web browsers. Since few if any reviewers would have the time, resources, or inclination to verify these claims, it should suffice to simply bear in mind that the script output and other behavior detailed in the book might not exactly match those experienced during one's own usage of the code.
The fact that there were several cooks in the kitchen brewing up this particular book, is obvious from the way that the code formatting is not consistent throughout the book, as well as the variety of problem-solving styles. Fortunately, neither weakness is of much consequence, and the latter might even be considered a "feature," as it allows the reader to see how a number of veteran PHP developers approach solving a problem.
Most technical works written by a team of authors, end up as excessive "doorstops" that are often frustrating to read as a result of the wildly inconsistent writing and coding styles, to say nothing of the material often being out of date as a result of the long production time needed by the publisher. The opposite case can be even worse, when a publisher releases a book that was clearly thrown together as quickly as possible to capitalize upon a hot new trend in technology. Thankfully, PHP Hacks keeps the style differences to a minimum, and benefits from having a lead author responsible for the book as a whole.
Some programming purists may take issue with the use of the term "hack" used as a synonym for a small PHP application or the use of such for solving a problem, since the majority of the PHP scripts in the book do not involve any programming or problem-solving that would be considered notably clever or elegant. Yet the misuse of the term seems to be spreading, and is not limited to this particular book ; another example of marketing overpowering stability of language. In the preface of PHP Hacks, the author explains that he uses the term in the positive sense of creative participation, to help reclaim it from its popular usage in place of the more traditional term "cracking," i.e., breaking into systems.
Yet aside from these complaints, PHP Hacks is a worthy title that offers explanations and source code for many valuable site-enhancing applications, testing and code generation techniques, and critical e-commerce safeguards. I recommend this book to any PHP developer who would like to add to their Web sites' capabilities, as well as their knowledge of what PHP can do.

PHP is a bunch of hacks.
And....? I presume if all the code samples were legal, such a statement would be unnecessary. I further presume such a statement to that effect would not warrant inclusion in a book review.
So just what is the aspect of the legality of the code samples in need of clarification? Is one of the 'hacks' phishing with PHP? Adding free copies to your Kinkos card? Downloading launch codes from the WOPR? They're using the PHP to cook up meth, aren't they? *peer*
What defines a "hack" these days.
Maybe I'm a bit bitter, and even at the risk of sounding like a troll I'm just gonna say it, isn't writing ANY decent amount of php kind of a hack.
Personally I'm a django fan, I really respect the rails kids for what they are doing too. Once you start doing web development in a real dynamic language you realize that web development in php in most cases IS a hack.
I've written lots of php over the years, and I'm so glad to know that I NEVER HAVE TO DO IT AGAIN. Unlike in other languages the "hacks" in php tend to be a necessity for doing development in the language. I've really tried to write "clean" code in php and it's just not possible for any project of a decent size.
Any disagreements?
it's just the fashion at the moment. Bashing Java is a classic, but PHP, like 80's ra-ra skirts and lip gloss, goes in and out of fashion constantly. Just stick to praising R-o-R, that'll keep the karma nice n' safe.
Yup, but this comes down to what all dicussions do when a PHP topic is posted to slashdot. Is it the fault of the language when a lot of open source applications are written poorly? There have been very few vulnerabilites in PHP, but lots in apps like Mambo, *Nuke, phpBB, etc.
I like PHP, I can develop stuff very quickly in it, and I know how to secure code against CSS, SQL-Injection, etc. There are shortcomings with it, like basically every other language, but I don't think the fact that all these application with vulnerabilities should be a direct reflection on the language itself.
"Advanced PHP programmer"? Now there's a contradition for you.
Lost: Sig, white with black letters. No collar. Reward if found!
anyone can tell me if this is to be taken seriously, or rather seen as worthless php-bashing?

Slashdot provides a place for reviews of technical books. They get to specify the URL and get referrer credit for it. The reson it is BN is because of the Amazon "One-click" patent, for which they sued BN - so using Barnes and Nobble both supports Slashdot, and provides a small way to fight obvious SW patents...
On the other hand, looks like the parent put their own referrer link to Amazon - now that's what I call cheating!
Yes. The language doesn't actually compel you to write insecure code, but it would be hard to imagine one which came closer. It's practically begging for injection everywhere. You need to manually escape everything. Database work? Sorry, no prepared statements. Going to send mail()? Leave a few newlines in the wrong variable and you can turn your form into a lean, mean spamming machine! Going to try and call system() with any sort of parameters? Quick check: do you want escapeshellcmd, or escapeshellarg? (and of course, you HAVE to use the shell.) There's more, much more, and if that's not enough, two words should make your skin crawl: "register globals".
use strict; use warnings; taint mode? In your dreams maybe... ... I think they used a shotgun on it.
Model-view-controller design?
GAAH.
The World Wide Web is dying. Soon, we shall have only the Internet.
Yes, PHP is relatively easy to begin coding in, what with its fairly forgiving variable typing (or what some would call non-typing) and its babysitting of memory. I would even agree that PHP tends to attract more bozos and wannabes for this very reason. However, PHP is, and continues to be the most widely used non M$ language for open sourced web applications. This is because it works. Sure, PHP allows sloppy coding, but it also allows clean and well written code. PHP is a lightweight, nimble, comprehendable scripting language that is very well suited for its intended environment: the web.

I understand that PHP has a very solid newbie user base, but let's not forget monstrous sites like Digg and Wikipedia run on PHP + MySQL
PHP seems to be one of those red-button topics on Slashdot. If the word even appears in the text of the story, the topic at hand is dropped entirely in favour of having a big wanking session and patting each other on the back for knowing a 'superior' language, or for having been into Linux 'before it was cool', or whatever the general topic happens to be.
And not only is this stuff offtopic, it's also just so painfully redundant. I swear, that Slashdot story generator page from a while back was pretty impressive, but I'm starting to think maybe I could cook up a Slashdot comment generator as an add-on.
PHP has had prepared statement support for MySQL since 2003, it's been emulated in PEAR for an eternity and the very useful PDO extension provides an abstracted interface supporting prepared statements to SQL Server, Sybase, Firebird, Informix, MySQL, Oracle, PostgreSQL, SQLite, DB2 and ODBC.
Forgive me, but you don't know what you're talking about. There is almost never a need to call external apps from a PHP script. The most common needed external app is ImageMagick (because sometimes GD doesn't provide all the functionality you need.) Even then, there are at least two PHP extensions to deal with ImageMagick directly, as well as a PEAR package to abstract away from the image processing library/app.
Well, I dunno, do you want to escape an entire command so that multiple commands can't be injected or do you want to escape a single argument so that multiple arguments can't be injected? Heaven forbid that you should have to spend ten seconds checking the manual pages...
So use one of the multitude of classes specifically written to encapsulate mail sending (including, shock horror, one in PEAR.)
register_globals has been disabled by default for six (6) years.
It's not the fault of the language that you didn't bother to keep up with how to use it as it evolved.
