十九、攻击任务（MissionCaseAttack.php）

按照舰队任务的编号，排在第一个的就是攻击任务。这个代码很长，看的时候要有耐心。
好在引用的内容并不是很多，并且给出了详细的注释，读者不会晕头转向。

   // 代表出发时间的是start_time
   // 此外还有fleet_end_time 这个是回到家的时间
    // fleet_end_stay 这个是结束逗留的时间（联合防御和远征任务会用到）
    // 所以下面这个判断的意思是“舰队到达了目的地”，而不是“舰队起飞了”
    if ($FleetRow['fleet_start_time'] <= time()) {
    // fleet_mess是用来记录舰队的状态的，基本可以理解为是在前进途中还是返航途中
    // 但感觉利用得并不好，如果只有两个状态，可以用true 和 false来记录
    // 所以我把它设为了0，1，2三个状态，对于需要停留的任务，停留时就处于第三个状态
