警告：	It is recommended you use the WANObjectCache service. However, if you really need the internal object, use ObjectCache::getLocalClusterInstance instead.

$wgMemc is the global variable used to access the main cache. It is set in Setup.php :

$wgMemc = ObjectCache::getLocalClusterInstance();

wfGetMainCache()

（在1.32版本中已弃用）

Past global function wfGetMainCache() defined in Manual:GlobalFunctions.php as follows:

function wfGetMainCache() {
	return ObjectCache::getLocalClusterInstance();
}
