5.0 out of 5 stars Definitive Reference May 13 2006
By Nathan Smith - Published on Amazon.com
Format:Paperback
If you are like me, you have probably dabbled in PHP and MySQL driven CMS solutions, simply because that combination is so prevalent. I consider myself to be primarily a front-end developer / graphic designer, and am not terribly interested in knowing every server-side language there is, so long as whatever I am using can get the job done. Suffice it to say that while I am eager to learn and expand my horizons, my exposure to more than LAMP has been limited.

So, when Jason Gilmore sent me a review copy of his latest book, that he co-authored with Robert Treat, I was glad to be learning about this powerful database. The title is Beginning PHP and PostgreSQL 8, and the structure of the text mirrors closely that of Jason's other best-selling book on PHP and MySQL 5, now in its second edition. To get a feel of the PHP aspect of both these books, read my other previous reviews on the First Edition and the Second Edition...
[...]

This saves me having to repeat myself, covering the PHP side of things as much. Suffice it to say that it is extensive and well worth reading. Now, allow me to focus on the second aspect of this book, PostgreSQL. While MySQL bosts being the world's most popular open source database, PostgreSQL has stake to the claim of being the world's most advanced open source database. Are these two in competition? Well, yes and no. I will expound further on that, but first a brief history lesson.

In 1986 at UC Berkeley, professor Michael Stonebreaker set out to build a better open source database than his previous project, called INGRES. Since the first project was a huge success, he decided to entitle the follow-up Post-GRES. So, while the first name was an acronym, Postgres is simply a derived nick-name that grew out of it. Postgres became so popular that providing tech support was becoming far too time consuming for Stonebreaker and his team. Eventually they ceased development to focus on teaching.

But, since it was released under the BSD license, development was picked up by Andrew Yu and Jolly Chen, who added in SQL functionality. Eventually this hybrid grew into the PostgreSQL database we know today. Their mantra has always been stability first, speed second. Whereas MySQL is built for responsiveness, PostgreSQL is designed to be rock-solid. This mentality is reflected in the choices of database mascots: a Dolphin vs. an Elephant.

You might have been hearing about PostgreSQL more lately because of the rising interest around the Django Project, which recommends PG as their database of choice. While it is of course driven by Python and not PHP, this further illustrates the scalable versatility of PostgreSQL. When reading this book, I was blown away by some of the server strain that PG can handle.

Consider these examples: Afilias Incorporated, the Internet registrar company responsible for managing the .info domain name extension, handles over 1000 database inserts per second! The NOAA weather service Weather.gov has scaled their operations across 150 PG servers. Whitepages.com runs PG databases exceeding 375 gigabytes with over 250 million rows. Big newspaper sites also run PG, such as Lawrence.com, KUSports.com and LJWorld.com.

Mega-churches such as FellowshipChurch.com also make use of PostgreSQL. When you have 20,000 people that go to your church, each one needing to check up on what's happening on a dynamically driven PHP website, that can be quite a server strain. To handle this, you either need an expensive proprietary platform, or a scalable open source solution. Fellowship opted to roll their own CMS and power it with PG.

Okay, so now you get the point that PostgreSQL is a force to be reckoned with. Allow me to touch briefly on the code aspects of what I thought was cool in this book. Robert has done a great job of flowing with Jason's proven writing-style. Many times, multi-author books differing topics can seem disjointed, but that is not the case here. He explains things very thoroughly without mincing words.

One of the cool features of PG is Multi Version Concurrency Control or MVCC for short. This allows "snapshots" of your database to be taken at set intervals, so that you can serve up cached data without repeatedly hitting the database, risking a hardware lock-up. This is commonly referred to as the "Digg Effect" or becoming a victim of being "Slashdotted," in which high-traffic websites send a flurry of incoming visitors to a lesser server which cannot handle the load.

PostgreSQL also supports MySQL style row-level locking, but the MVCC method is preferred because of its stability. Another nice feature is the ability to store commonly used queries, and even create abbreviations for frequently called procedures. You could think of it like referring to a best friend by a nick-name. This set of features has been native to PG for some time now, and is something that MySQL has recently implemented as of version 5.

The way I think of the differences between MySQL and PostgreSQL is that PG is a more transactional database. Meaning, if you want large enterprise level sites that handle many insertions and modifications throughout any given day, PostgreSQL is probably the way to go. MySQL can do this with with the InnoDB table type, but PG has better native support for it. PG also sports Foreign key support, Views, Stored procedures, Triggers, Unions and Full joins.

On the flip-side of that coin is that MySQL is typically a bit faster, has a more simplified database layout, and does not require vacuuming. Vacuum is a command that must be run from time to time, and typically is set as an automated process. One of the ways PG maintains consistent stability is through the previously mentioned MVCC method, which disperses duplicate data in order to avoid hitting one particular location repeatedly. Periodically, these duplicates need to be reigned in or vacuumed, to clean up disk space.

In comparing PostgreSQL with MySQL side by side, there is not a clear-cut winner, because it is a bit like comparing apples and oranges. If you want a fast and responsive site, MySQL is probably the way to go. If you are managing one that has a high amount of traffic and needs to handle enterprise level or "mission critical" data, PostgreSQL should be one of the solutions you consider. I think of it this way: MySQL is a ninja, PostgreSQL is a samurai. One is quick and nimble, the other more heavily armored. If you want to learn more about the latter, then this is the book for you; Also available as an eBook, PDF file from the Apress website...

5.0 out of 5 stars Beginning PHP Not Beginning Programming June 17 2006
By David Stapleton - Published on Amazon.com
Format:Paperback
I read this edition after Gilmore's earlier book on PHP and MySQL, so let me quote the pertinent parts of that review and augment with appropriate comments:

A beginning PHP book, not a beginning programming book. The subtitle, 'From Novice to Professional', can be a tad misleading for the novice coder. A beginning programming book covers a lot of material that this book assumes the reader already understands. Many software books include a 'Who Is This Book For' section that offers some guidance on the suitable reader knowledge level, not this one.

That said, I found this book to be very helpful. The sections on installing and configuring Apache, PHP and PostgreSQL certainly saved me many hours of reading the online documentation and tweaking of settings while setting up my local test bed. That, in itself, made me a very happy camper. The author goes on to cover the various aspects from the basics of the PHP language and class libraries to topics like Authentication, Security, Session Handlers and eMail functionality that help anyone new to PHP setup some fairly sophisticated site capabilities.

Gilmore has included a section on PEAR (PHP Extension and Application Repository). This is a wealth of prewritten classes and packages that can be used to add even more sophisticated functionality to the novice's web development toolbox. The author demonstrates several of the more prominent packages.

New for this edition, Robert Treat has contributed coverage of PostgreSQL, including chapters on tables and data types, views, functions, indexes and triggers. There is also coverage of the more pertinent PHP functionality to access PostgreSQL. Most of the examples offered are clean and general enough to be useful templates for the reader's tailoring.

My suggestion for novices to PHP is read through chapter 9, then skip to the various sections that solve specific problems being faced or are of particular interest, including installing and configuring your local test bed.

Bottom line, this edition was a good book for intermediate to veteran programmers looking for a quick tutorial on PHP (circa version 5.1) and specifics for the PostgreSQL community. Novice programmers should ensure that they have a full understanding of the basics of programming (and OOP) before attempting it.

4.0 out of 5 stars Packed with Information April 24 2006
By Joseph Topjian - Published on Amazon.com
Format:Paperback
Divided into two parts, Beginning PHP and PostgreSQL 8 teaches all the fundamentals of these two technologies from the ground up. Part One is a massive text that covers absolutely everything about PHP: installation, data types, PEAR, Smarty, Objects, and more.

Part Two is all about PostgreSQL. Though it's much shorter than Part One, it's just as feature packed. Installation, client utilities, advanced data types, triggers, views, and interfacing with PHP are just some of the topics covered.

This book definitely has a lot of content. If read from beginning to end, there's no doubt that any newcomer will have a better understanding about these two technologies. I do have one complaint though: I found the style of writing to be too much like a reference manual. Although this /is/ a technical book, I think a different approach would appeal more to beginners. Maybe content with more events and actions to build full projects would help. Other than that, I think this is a great book for beginners - especially those curious about PostgreSQL.

2.0 out of 5 stars Supposed to be a PHP-PostgreSql not Smarty-Pear July 20 2007
By D. Trent - Published on Amazon.com
Format:Paperback
What's annoying about this book is that I bought it to learn more about PHP and PostgreSQL but the authors decide to use Smarty and PearDB throughout instead. If I wanted to learn those two I would have bought books about them. Smarty and PearDB is used in every single piece of code they do which is extremely annoying. I don't want to learn Smarty or PearDB. If you're trying to learn PHP and PostgreSQL don't buy this book. If you want to learn Smarty and PearDB this book might be for you.

5.0 out of 5 stars Excellent coverage of the basics Aug. 6 2009
By Ryan Kulla - Published on Amazon.com
Format:Paperback|Verified Purchase
This book has outstanding coverage of the basics of PHP and Postgres 8 administration and usage. It is intelligently written and talks about the things you'll actually need to know when working with these technologies. I've had it for a couple years and still use it as a reference. If you want something more advanced, then get "Pro PHP" by Keven McArthur.
