Dzx retrieves data from the common_syscache table, stores the obtained data in the cache, and caches the data as needed.
I studied it again today and found that dzx has saved the cached data in the large global variable $ _ g.
Another example is about cache update of dzx.
Dzx uses the updatecache function of source \ function \ function_cache.php to update the cache. It introduces the corresponding files under source \ function \ cache according to the cache project to be updated specified in the function parameters, only one function whose name starts with build_cache _ is defined, and then call_user_func is used to call these functions.
Every build_cache _ *** function uses the save_syscache method to save the data in the common_syscache table.
