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)
You are reading the second segment of the four-part article series covering MySQL benchmarking concepts and strategies, benchmarking tools and utilities, and the most common query optimizations, design of optimal schemas, and server tuning tips. In this part we will present some of the popular benchmarking and monitoring tools and utilities. By the end of this article, you’ll know how to use and work with each of them.
In our last article we introduced the subject of database security. In this article we will continue to explore various attacks that can be made on a database and how to prevent these attacks. We will also build the last page of our site. This article is the conclusion to an eight-part series.
