Hello! I'm new to PHP and I'm having this kind of problem. There are two files, main.html and test.php. Main.html collects information about the user, test.php should display questions that are in a text file, but instead of them, an empty window. How to fix the problem?
Text file of the form:
Question 1 2+2 = ?
a)
b)
c)
d)
Question 2.
Code:
Main.html

<!DOCTYPE html>
<html lang="ru">
<head>
    <meta charset="UTF-8">
    <title>Страница регистрации</title>
    <h3 align = "center">Добро пожаловать!</h3>
</head>
<body>
<form accept-charset="UTF-8" action="test.php" method = "POST">
    <table border = "1" align = "center">
       <tr><td>Фамилия</td><td><input type = "text" name = "surname"></td></tr>
       <tr><td>Имя</td><td><input type = "text" name = "name"></td></tr>
        <tr><td>Пол</td><td><input type = "radio" name = "sex" value = "m" >М
            <input type = "radio" name = "sex" value = "f" >Ж</td></tr>
        <tr><td>Цифра класса</td>
           <td>
               <select name = "class">
                   <option value = "8">8</option>
                   <option value = "9">9</option>
                   <option value = "10">10</option>
                   <option value = "11">11</option>
               </select>
           </td>
        </tr>
    </table>
    <input align="center"  type = "submit" value = "OK">
</form>
</body>
</html>

test.php

<!DOCTYPE html>

<?php
