Laravel，除以零

Question

我正在尝试获取在玩游戏时退出的玩家百分比，所以我有错误：除以零。按标准在游戏中0个参与者，0个退出玩家。 在刀片中：{{ $withTotal }}，在控制器中

$withTotal = $this->getWithPerc();
return view('pages.crash', compact('withTotal'));

private function getWithPerc()
    {
      $withUsers = CrashBets::where(['round_id' => $this->game->id, 'status' => 1])->count();
      $NowithUsers = CrashBets::where(['round_id' => $this->game->id, 'status' => 0])->count();
      $totalUsers = $withUsers + $NowithUsers;
      $next1 = $totalUsers / 100;
      $next2 = $withUsers / $next1;
      return $next2;
    }

在游戏下注后开始获取参与者和退出游戏的人数。所以在这之后我得到了这个错误。我该如何解决这个问题？谢谢大家:)

您可以在进行第二次操作之前检查 $next1 是否不为零：解决方案如下：

private function getWithPerc()
{
  $withUsers = CrashBets::where(['round_id' => $this->game->id, 'status' => 1])->count();
  $NowithUsers = CrashBets::where(['round_id' => $this->game->id, 'status' => 0])->count();
  $totalUsers = $withUsers + $NowithUsers;
  $next1 = $totalUsers / 100;

   if($next1 == 0) 
       return 0;

  $next2 = $withUsers / $next1;
  return $next2;
}
