PHP and MySQL for scalable Web applications

Scalability is an important consideration in building web applications. Scalability generally refers the ability to handle increasing traffic load. Traditionally, PHP has not been considered very scalable. However, it has more to do with how applications PHP is written in the past rather than a limitation in PHP. WordPress and Drupal are excellent examples of scalable applications built in PHP. The expansion of their application PHP and MySQL Web is simply to follow some of the practices used in WordPress and Drupal.

Employ Modular Design
Construction a modular application is a sure way to expand your web application with PHP and MySQL. If you examine the code of WordPress, you can find that has been built in a very modular. All database code in one place. All code and design representation in another. There are places in modules to add additional functions called hooks and filters. This makes it easy to extend WordPress without recoding parts of the underlying application. This modular architecture makes it easy to scale a Web application with PHP and MySQL.

Maintaining levels of abstraction
Abstraction is another important consideration. The more higher the level interfaces to abstract things code and access to the database. The functions to retrieve the data have features that just "go" the data without knowing the underlying details. This is important to extend your Web application with PHP and MySQL, since it is not known in advance how the database has been implemented. You might initially deploy your PHP code on the same server as the MySQL database. Later, MySQL could be on a separate server. And even later, it is possible balancing the load across multiple MySQL servers. Changing the underlying architecture that requires only minimal changes way of doing two things above and ensure scalability of PHP and MySQL web application is the use of a frame. There are many PHP frameworks that follow the Model-view-controller used in systems like Ruby on Rails. These frameworks already provide a modular and robust abstraction layer database. Some of them also support caching and manage database sessions data to maximize its ability to extend your Web application with PHP and MySQL.

Cache, cache, cache!
Speaking of memory cache, a common technique for scaling web applications with PHP and MySQL is to use a caching data or content page that does not change frequently. Think about how you can use caching in the future as you develop your application. If you can separate the data and pages that can be caching which may not, have an easier time using a cache to scale the Web application with PHP and MySQL.

Scalability is a important consideration in web development today. There are a number of techniques for expanding its Web application with PHP and MySQL. The modular design, abstracting underlying details, using a framework and taking into account About the Author
