An Introduction to PDO
A common complaint of the anti-PHP “expert” is the lack of a bundled, uniform database access component. With the advent of an improved object model, in PHP 5.0, a few of PHP’s core developers decided that the time has come to fill this hole with PHP Data Objects (PDO). The package, itself, has been in PECL for quite a while, now, but with the upcoming release PHP 5.1, PDO will be bundled in the main PHP distribution. What does it do? How does it work? One of PDO’s main developers, Ilia Alshanetsky, explains.
Roll Your Own Data Abstraction Module
You may already use database abstraction in your applications, perhaps through one of the available data-base abstraction layers, such as PEAR::DB, or PDO (see the PDO article in this issue), but what about various idiosyncrasies in the actual SQL?

Security Corner: PHP Security Audits
Peer reviews are one of the most useful and underutilized development techniques. Although professional security audits tend to be quite expensive, peer reviews can offer a great deal of value at a decreased cost. With a moderate understanding of how to audit PHP code, you can be a valuable asset to any PHP development team, and columnist Chris Shiflett shows you how.
Test Pattern: State of Confusion
Bug-free code is code you can understand completely. Unfortunately, it doesn’t take much to cause us uncertainty. Even a small amount of complexity will place demands on our memory, and our memory is extremely limited. If we tax our brains, we will get bugs. Marcus Baker examines how the number of bugs in a piece of code can be correlated to its readability.
