Saving value of radion buttons in different variables

[jamhussain]

if I submit the HTML Form in action.html file.
this html Form has some Radio Buttons.
the value of selected radio button is received in action.php file.
I want to save this value in a variable.
if I submit the Form again with different radio button selection, then it should be saved in another variable.
in this way, if I have there radion buttons , then I should have three different variables.
How can I get it.How can save its value in one variable for complete sesseion.thanks.

I would suggest a hidden field with a count of the number of submissions.
For instance the first time the form is show you would have:
<input type="hidden" name="counter" value="1">
Your session value for the first submission would be for instance:
$k=$_POST['counter'];
$_SESSION['var'.$k]=$_POST['radiofield'];

Where radiofield would be the name of your radio buttons.
