discuz x2.5中关于discuz_database类的问题

	public static function delete($table, $condition, $limit = 0, $unbuffered = true) {		if (empty($condition)) {			return false;		} elseif (is_array($condition)) {			if (count($condition) == 2 && isset($condition['where']) && isset($condition['arg'])) {				$where = self::format($condition['where'], $condition['arg']);			} else {				$where = self::implode_field_value($condition, ' AND ');			}		} else {			$where = $condition;		}		$limit = dintval($limit);		$sql = "DELETE FROM " . self::table($table) . " WHERE $where " . ($limit ? "LIMIT $limit" : '');		return self::query($sql, ($unbuffered ? 'UNBUFFERED' : ''));	}该方法中的$where = self::format($condition['where'], $condition['arg']);21.$condition['arg']是什么意思指什么？

回复讨论(解决方案)

数组里的一个键值

他应该 是这样的 delete删除方法 里面 肯定要条件 这个方法内部 最这个条件格式花下 在拼接成最后的sql 至于$condition['arg'] 你直接打印下 不就知道了 .....
