public function getGroups($uid) {
static $groups = array();
if (isset($groups[$uid]))
return $groups[$uid];
$user_groups = M()
->table($this->_config['AUTH_GROUP_ACCESS'] . ' a')
->where("a.uid='$uid' and g.status='1'")
->join($this->_config['AUTH_GROUP']." g on a.group_id=g.id")
->field('uid,group_id,title,rules')->select();
$groups[$uid]=$user_groups?:array();
return $groups[$uid];
}里面的 "a"是什么意思呢？没有看懂，table($this->_config['AUTH_GROUP_ACCESS'] . ' a') 最佳答案
