how to get multiple radio button values in php

Question

I have a webpage that contains two set of radio buttons. I want to do; if user select a OS in first fieldset and a language from second fieldset, then user must directed to relevant pages.

Please guide me to complete this page. I am unable to get two radio button values at a time. If I rename the radio buttons like below,

<fieldset id="group1">
    <input type="radio" class="radto" name="android"/>
</fieldset>
<fieldset id="group1">
    <input type="radio" class="radto" name="english"/>
</fieldset>

It's working, but the problem is users can select more than one OS and language. I need to prevent this. How can I overcome this problem.

<?php
if (isset($_POST['submit'])) {
    if (isset($_POST['android']) && isset($_POST['english'])) {

        header("location: andro_eng.php");
        exit();
}

    if (isset($_POST['android']) && isset($_POST['french'])) {

        header("location: andro_fre.php");
        exit();
    }
}

?>

<html>
<head>
</head>

<body>
<form action="" method="post">
<fieldset id="group1">
    <li><input type="radio" class="radto" name="a"/>&nbsp;   &nbsp;android</li>
    <li><input type="radio" class="radto" name="a"/>&nbsp;   &nbsp;ios</li>
    <li><input type="radio" class="radto" name="a"/>&nbsp;   &nbsp;symbian</li>
</fieldset>

<fieldset id="group2">
    <li><input type="radio" class="radto" name="b">&nbsp; &nbsp;english</li>   
    <li><input type="radio" class="radto" name="b" >&nbsp; &nbsp;french</li>
    <li><input type="radio" class="radto" name="b">&nbsp; &nbsp;spanish</li>
</fieldset>
<input type="submit" value="next" name="submit">
</form>
</body>
</html>

PHP isn't causing the issue. A lot of people can help unfortunately aren't looking at this question because they think it involves PHP and they don't know PHP. Just a helpful tip! — Goose

The name attribute has to be the same for the different options:

$( document ).ready(function() {
  $('#button').click(function() {
    alert($('input[name=os]:checked').val()); 
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<fieldset id="group1">
<input type="radio" class="radio" name="os" value="android" id="android" />
<label for="a">Android</label>
</fieldset>
<fieldset id="group1">
<input type="radio" class="radio" name="os" value="iOS" id="iOS" />
<label for="b">iOS</label>
 </fieldset>

<button id="button" type="button">Get value</button>

And you need to add a value attribute to the radio inputs, otherwise you won't get any value.

Then you can get the values from PHP: $_POST['os'] will return android, iOS or may be empty if no value is selected.

Check the $_POST["a"] and $_POST["b"] (which are the name property of your radio buttons). They will be filled by the selected value associated to the selected button. You must add the value property to your HTML like : <input type="radio" class="radto" name="b" value="spanish"/>Spanish

@Dom which are the name property of your radio buttons No, the name is android. I have updated the answer in order to provide a better example.
