What are the recommended best practices for disabling cache in the Magpie parser to prevent old data from being displayed?

When using the Magpie parser in PHP, it is recommended to disable caching to prevent old data from being displayed. This can be done by setting the cache to false in the Magpie configuration. By disabling caching, the parser will always fetch the latest data from the source feed, ensuring that outdated information is not displayed.

// Disable caching in Magpie parser
define('MAGPIE_CACHE_ON', false);
