19. Attack Mission (MissionCaseAttack.php)

According to the fleet mission number, the first one ranked is the attack mission. This code is very long, so be patient when reading it.
Fortunately, there are not many quotes, and detailed notes are given so that readers will not be confused.

   // 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
