The best way I see to do this would be to create an answer and question script with a common configuration file.

Here is an example:

Common file (both included by answer and question scripts). This will have the questions and answers. Example:

		Code 			
<?php
<br />

<br />
// Create an array with the questions and answers
<br />
$quiz_questions = array (
<br />
	// The first element of the array is the correct answer (so 'Answer2' is correct in the question below)
<br />
  'Question 1' => array('2','Answer 1','Answer2','Answer 3'),
<br />
  'Question 2' => array('1','Answer 1','Answer 2','Answer 3','Answer 4'),
<br />
  'Question 3' => array('1','Answer 1','Answer 2')
<br />
);
<br />

<br />
?>	

The question file will use a loop to print out each question:

		Code 			
<?php
<br />

<br />
// Include the common code
<br />
include("quiz_common.php");
<br />

<br />
// Initialize a form
<br />
echo '<form action="quiz_answer.php" method="post">';
<br />

<br />
// Use foreach to grab each question from the $quiz_questions array
<br />
$x = 1; // $x will keep track of the question number
<br />
foreach ($quiz_questions as $question => $answers) {
<br />
	echo "<b>$x. $question</b><br />\n";
<br />
	
<br />
	array_shift($answers); // Remove the first element (the answer) from $answers
<br />
	
<br />
	$y = 1; // $y will keep track of the answer letter
<br />
	foreach ($answers as $answer) {
<br />
		// Print radio button
<br />
		echo "<input type=\"radio\" name=\"question_$x\" value=\"$y\" />" . chr($y + 96) . ") $answer<br />\n";
<br />
		$y++;
<br />
	}
<br />
	$x++;
<br />
	echo '<br />';
<br />
}
<br />

<br />
// Submit button and end form
<br />
echo '<input type="submit" value="Check Answers" />
<br />
	</form>';
<br />

<br />
?>	

The answer file will also use the array to check the answers:

		Code 			
<?php
<br />

<br />
// Include the common code
<br />
include("quiz_common.php");
<br />

<br />
// Use foreach to loop through each question
<br />
$x = 1;
<br />
foreach ($quiz_questions as $question => $answers) {
<br />
	echo "<b>$x. $question</b><br />\n";
<br />
	
<br />
	// We'll assume the answer is correct unless one of the checks below fails
<br />
	$incorrect = FALSE;
<br />
	
<br />
	// Print their answer
<br />
	if ($_POST["question_$x"]) {
<br />
		echo "You chose " . chr($_POST["question_$x"] + 96) . ") which is ";
<br />
		if ($answers[0] != $_POST["question_$x"]) { echo 'incorrect. '; $incorrect = TRUE; }
<br />
		else { echo 'correct.'; }
<br />
	} else {
<br />
		echo "You did not answer this question. ";
<br />
		$incorrect = TRUE;
<br />
	}
<br />
	
<br />
	// If the answer is incorrect print the correct answer
<br />
	if ($incorrect) {
<br />
		echo "The correct answer is " . chr(96 + $answers[0]) . ") {$answers[$answers[0]]}.<br />";
<br />
	}
<br />
	
<br />
	$x++;
<br />
	echo '<br />';
<br />
}
<br />

<br />
?>
