Namespaces are an elegant approach to solving naming conflicts between the classes that are used by a PHP application. Indeed, it’s pretty common to suffer this problem during the development of a project that’s been charged to several programmers, and also when working with third-party libraries. This four-part series of articles, of which this is the last, shows you how to handle namespaces. Discuss (1)
Anyone who has programmed for any length of time has encountered the concepts of null and empty strings. They are not the same, and confusing the two can cause some serious problems. This article deals with these concepts in the context of PHP and MySQL. Discuss (2)
In this article we will continue to discuss the application-wide scripts that we started to talk about in the last article. These special scripts are used by all the scripts and pages of the application. We will continue to look at the func.inc script that has several useful functions defined in it. This article is the third part of a nine-part series.
The release of PHP 5.3 is just around the corner. This version of the language comes with a lot of useful features that will put a smile on the face of many programmers. One major improvement it introduces is support for namespaces. This feature permits users to work independently with classes that share the same name, facilitating the development of object-oriented applications that use third-party libraries.

Fine-tuning the settings of servers in general requires a strong grasp of the inner workings of the servers and lots of patience. Did we mention patience? Yup, we did. It’s really important to understand that there are no tips that work for all kinds of setups. But thankfully we can talk about some widely known guidelines that can be followed to get the most out of your MySQL servers.
Any application that is security critical will have some kind of method to track and maintain user activity. In this article we will begin to build a user management system that will give us control over who has access to which part of our application. This is the second part of a nine-part series.

Namespaces have been available for a long time in mature object-oriented languages like Java and C++. However, there’s good news on the horizon, since they will also be available in PHP 5.3 (hopefully). That’s a good reason to start learning how to use them within the context of object-oriented PHP applications. This is the second part of a four-part series that shows you how. Discuss (1)
Performance is something for which we all strive. This applies to the lives of DBAs too, since their first and foremost task is to achieve a high level of performance from their databases. SQL professionals can’t stress enough that spending quality time to optimize both schema design and queries should be considered top priorities. In this article we are going to cover these two.
In this article we will look at how to create a secure user management module. No user authentication or user management script can ever be one hundred percent secure, but we can try to use the tools that are available to us to their maximum, and thereby make it difficult for malicious users to hack our scripts.

Namespaces were created as part of PHP 5.3 to solve certain conflicts that can arise when two different classes are given the same name. This situation comes up more commonly than you might think. This four-part series introduces you to using namespaces to solve these and similar issues. It includes copious code examples to enhance your understanding. Discuss (5)
