discuz secondary development notes (1) ------$_G full analysis, discuz_g

$_G saves all preprocessed data in Discuz!
Caching can greatly improve the performance of the program. There is no need to query the database every time for some configuration data. You only need to update the cache when it is modified.
All caches in Discuz! are stored in $_G[cache]
$_G[member] Member information data
$_G[uid] User uid
$_G[username] User name
$_G[adminid] User management group id
$_G[groupid] User group id
$_G[setting] Setting data
$_G[cache] System cache
$_G[cache] [plugin] Plug-in cache
To load the cache, you can use the loadcache() function to load the cache into the $_G[cache] array
