Symfony 1.3 Web Application Development

Overview of this book

With its flexible architecture, the Symfony framework allows you to build modern web applications and web services easily and rapidly. The MVC components separate the logic from the user interface and therefore make developing, changing, and testing your applications much faster. Using Symfony you can minimize repetitive coding tasks, optimize performance, and easily integrate with other libraries and frameworks. Although this framework contains with many powerful features, most developers do not exploit Symfony to its full potential. This book makes it easy to get started and produce a powerful and professional-looking web site utilizing the many features of Symfony. Taking you through a real-life application, it covers all major Symfony framework features without pushing you into too much theoretical detail, as well as throwing some light on the best practices for rapid application development. This book takes you through detailed examples as well as covering the foundations that you will need to get the most out of the Symfony framework. You will learn to shorten the development time of your complex applications and maintain them with ease. You will create several useful plug-ins and add them to your application and automate common tasks. The book also covers best practices and discussions on security and optimization. You will learn to utilize all major features of this framework by implementing them in your application. By the end, you should have a good understanding of the development features of Symfony (for Propel as well as Doctrine editions), and be able to deploy a high-performance web site quite easily.

Caching


As seen in the previous section, using HTTP compression is a step in the right direction. But we should really look at how to speed up Symfony before the final content is compressed and delivered. The solution to this is the use of caching. To limit the amount of processing required, Symfony offers a caching framework. Basically, it stores chunks of your code as native PHP in a temporary file. But it is not just the amount of processing that is saved through the framework. Result sets fetched from the database too can be cached, which means less connections to the database server and less processing by the database server too. By default, these temporary cache files are stored in the cache/ folder, which we touched upon while creating the back office.

Essentially, Symfony will first check the cache directory before processing the configuration. If caching is enabled, there is no need to execute the action that ultimately speeds up the response and/or the layout. However, this will...
