Once you submit that form to PHP all your radio box values will be available in the $_POST array by their name (i.e. $_POST['Answer1'] would have a value of LID1_1 or LID1_2 depending on which answer was selected. From there you just need to do a conditional if statement if($user_answer = $correct_answer)

To expand a little on GliderPilots excellent answer ...

<?php
// Set default values.
$score = 0;
$tried_answer1 = "";
$tried_answer2 = "";
$correct_answer1 = "LID1_2";
$correct_answer1 = "LID2_1";

// Get POST values.
$tried_answer1 = $_POST['Answer1'];
$tried_answer2 = $_POST['Answer2'];

// Compare answers.
if ($tried_answer1 == $correct_answer1){
    $score += 1; // Add score
}
if ($tried_answer2 == $correct_answer2){
    $score += 1;
}

// Display score.
echo "Score: " . $score;
?>

Line 7 above should be:

$correct_answer2 = "LID2_1";
