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.
Welcome to the final part of the four-part series “Subclassing exceptions in PHP 5.” By means of a hands-on approach, this series walks you through using inheritance to build finely-tuned exception subclasses. These subclasses can be used to handle, via multiple “try-catch” blocks, several failures that might occur during the execution of a given web application. Discuss (1)
MySQL is the world’s most popular open source relational database management system (RDBMS). As a result, over ten million installations are spread around the globe. Nevertheless, in reality only a small percentage of those are actually high performance, optimized, and tuned servers. This four-part article series targets the MySQL database and system administrators, covering various strategies to help benchmark and optimize databases, and tune servers to yield an outstanding performance.
In this article we will discuss security for databases accessed through the Internet. We will also examine the issue of password management, since handling that task properly will help us make our web site and its applications more secure. This is the seventh part of an eight-part series that shows you how to build security into an application for an Internet cafe. Discuss (2)
If you’re a PHP developer who wants to learn the basics of implementing customized exceptions in PHP 5, then look no further, because you’ve come to the right place. This is the third part of a four-part series entitled “Subclassing exceptions in PHP 5.” It teaches you how to extend the native exception mechanism bundled with PHP 5 by using inheritance, and complements the corresponding theory with copious, illustrative hands-on examples.
