PHP网页游戏学习之Xnova(ogame)源码解读（十六）
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

// 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
