How to view all WP-Cache cached content in WordPress?

In WordPress, use wp_cache_set() Functions can store data in the cache, but WordPress does not provide the ability to directly view all cached data. However, you can do this using a WordPress plugin or writing the code yourself.

Here are some methods for reference:

1. Use plugins

Some WordPress cache plugins, such as WP-Optimize, WP Rocket, etc., provide the function of managing cache and viewing all data currently in the cache. You can install these plug-ins and view cached data through the plug-in interface.

2. write code

If you want to write your own code to look into the WordPress cache, you can use the following function:

• wp_cache_get( $key, $group = '', $force = false ): Get data from cache.
• wp_cache_delete( $key, $group = '' ): Delete the specified data from the cache.
• wp_cache_flush(): Clear all data in the cache.

You can use these functions in the code you write to get, delete, or clear cached data. The specific implementation method needs to be determined according to your specific needs.

It should be noted that it is not recommended to use self-written code to view cached data in a production environment, as this may cause security issues. It is recommended to use it in a development environment and remove the relevant code promptly after debugging.
