PHP切换大小写大于1的情况下 [英] PHP switch case more than 1 value in the case

问题描述

我有一个变量来保存值(每周"，每月"，季度"，年度")，并且我还有另一个变量来保存值从1到10.

I have a variable that holds the values ('Weekly', 'Monthly', 'Quarterly', 'Annual'), and I have another variable that holds the values from 1 to 10.

switch ($var2) {
       case 1:
          $var3 = 'Weekly';
          break;
       case 2:
          $var3 = 'Weekly';
          break;
       case 3:
          $var3 = 'Monthly';
          break;
       case 4:
          $var3 = 'Quarterly';
          break;
       case 5:
          $var3 = 'Quarterly';
          break;
       // etc.
}

它并不漂亮，因为我的代码有很多重复项.我想要什么:

It isn't beautiful, because my code has a lot of duplicates. What I want:

switch ($var2) {
       case 1, 2:
          $var3 = 'Weekly';
          break;
       case 3:
          $var3 = 'Monthly';
          break;
       case 4, 5:
          $var3 = 'Quarterly';
          break;
}

如何在PHP中做到这一点?先感谢您.对不起，我的英语.

How can I do it in PHP? Thank you in advance. Sorry for my english.

推荐答案

最明智的方法也许是:

switch ($var2) {
       case 1:
       case 2:
          $var3 = 'Weekly';
          break;
       case 3:
          $var3 = 'Monthly';
          break;
       case 4:
       case 5:
          $var3 = 'Quarterly';
          break;
}

也可以在更复杂的情况下使用:

also, possibile for more complex situations:

switch ($var2) {
    case ($var2 == 1 || $var2 == 2):
        $var3 = 'Weekly';
        break;
    case 3:
        $var3 = 'Monthly';
        break;
    case ($var2 == 4 || $var2 == 5):
        $var3 = 'Quarterly';
        break;
}

在这种情况下，必须设置$ var2，并且不能为null或0

in this scenario, $var2 must be set and can not be null or 0
