Boost PHP Site Performance with Zend Framework Data Caching

"I'm currently wrapping up a fairly large Zend Framework-driven project that mines data from the Amazon Product Advertising API. According to the API license agreement, this data can be cached for a period of up to 24 hours. Therefore, I've created several database tables to store the data, and I employ a number of CRON-driven scripts to rebuild the data store once daily.

"However, because the product data will not change during that 24-hour period, it doesn't make sense to repeatedly execute the fairly complex JOIN queries and looping statements required to retrieve and format the data. Instead, I used the Zend_Cache component to cache this data, expiring the cache just ahead of the daily update. In this article I'll show you how to use Zend_Cache to cache your own data, considerably boosting your website performance in the process.

"Configuring Zend_Cache

"Zend_Cache can be configured to cache several types of output, including the results of function calls, the results of object and static method calls, entire pages, and configuration data. You determine what data is cached using Zend_Cache's frontend. This data can be cached in several ways, including using system memory (RAM), using memcached, within text files, or within a SQLite database. You determine exactly how your data is cached using Zend_Cache's backend."
