Forms work in PHP

I understand this form when choosing one of the options should be sent that the Question variable assigns the value of Second or First. That’s right?

Yes Radio Points with the same name form a group of buttons and this name is assigned to the Value button of the selected button.

So it is enough just:

<form method="POST" action="/index.php">
<input type="radio" name="question" value="first" checked> 1  
<input type="radio" name="question" value="second"> 2 
<input type="submit" value="">
