Question

我目前正在创建在线测验。为了让我从输入中检索信息，我想我需要为单选按钮输入一个值。我希望输入第一个值为1，第二个值为2等等。因为我在php中使用了这个echo，我假设它必须是某种变量？

我尝试过不同的循环，但我似乎无法让它发挥作用。很抱歉，这听起来像一个简单的问题。任何帮助，将不胜感激！

我改变了你的代码如下：

foreach ($questionInfo['options'] as $option => $desc) 
{
   $key++;
   echo "<input value='".$key."' type= 'radio' name = " . $questionNo  .      " >" . $desc . "<br>";
}
