PHP consultant Jason Gilmore worked on a large Zend Framework-driven project that mined data from the Amazon Product Advertising API, and he used the Zend Framework's Zend_Cache component to cache the data. In his PHPBuilder article, Boost PHP Site Performance with Zend Framework Data Caching, Gilmore shares what he learned from the project, explaining how to configure and use Zend_Cache for various types of data caching. He writes:
Zend_Cache can be configured to cache several types of output … You determine what data is cached using Zend_Cache's frontend. You determine exactly how your data is cached using Zend_Cache's backend.
Caching is one of the easiest and most effective ways to boost a website's performance, and Zend_Cache can make implementing it in your PHP projects simple.
