动态单选按钮 PHP

Question

I am currently creating an online quiz.我目前正在创建一个在线测验。 In order for me to retrieve information from the input, I think I am required to input a value for the radio button.为了让我从输入中检索信息，我认为我需要为单选按钮输入一个值。 I wish to input the values as 1 for the first, 2 for the second etc. Since I have used this echo in php, I am assuming it has to be some sort of variable?我希望将值输入为 1 用于第一个，2 用于第二个等。由于我在 php 中使用了这个 echo，我假设它必须是某种变量？

I have tried different loop but I can't seem to get it working.我尝试了不同的循环，但我似乎无法让它工作。 Sorry if this sounds like an easy question.对不起，如果这听起来像一个简单的问题。 Any help would be appreciated!任何帮助，将不胜感激！

i changed your code as follow:我将您的代码更改如下：

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