获取单选按钮值以在 PHP 中的开关语句中使用 - Obtaining radio button values for use in switch statement in PHP

Obtaining radio button values for use in switch statement in PHP

我很难弄清楚

如何获取单选按钮的值以用于 switch 语句。基本上，当用户选择其中一个单选按钮时，我希望执行该单选按钮的操作。不确定我是否正确设置了。我正在自己学习PHP，不知道这是否是正确的方法。下面是HTML和PHP。

<input class="radio" type="radio" name="calculate" value="average" checked="checked">Average<br />
<input class="radio" type="radio" name="calculate" value="total">Total<br />
<input class="radio" type="radio" name="calculate" value="both">Both<br />

这是 PHP

$calculate_type = $_POST['calculate'];
    switch ($calculate_type) {
        case '$calculate_type == "average"':
            $score_average = $score_total / count($scores);
            break;
        case '$calculate_type == "total"':
            $score_total = $scores[0] + $scores[1] + $scores[2];
            break;
        case '$calculate_type == "both"':
            $score_average = $score_total / count($scores);
            $score_total = $scores[0] + $scores[1] + $scores[2];
            break;
    }

你到底是从哪里学会写这样的switch语句的???

switch($calculate_type) {
  case "average":
    // do something
    break;
  case "total":
    // do something else
    break;
  case "both":
    // do something completely different
    break;
  default: die("Invalid type");
}

再说一次，在这种情况下，最好如下：

.HTML：

<input class="radio" type="radio" name="calculate" value="1" checked="checked">Average<br />
<input class="radio" type="radio" name="calculate" value="2">Total<br />
<input class="radio" type="radio" name="calculate" value="3">Both<br />

.PHP：

if( $_POST['calculate'] & 1) $score_average = $score_total / count($scores);
if( $_POST['calculate'] & 2) $score_total = $scores[0]+$scores[1]+$scores[2];
