Some problems for my new UCP

[Corsaro_Quad]

Hi. Today I'm working for a quiz with random questions but how can I do an answer checker?

This is the function:

function onRandomQuestionQuiz()
	{
		$tot_question = 75;
		switch(rand(1, $tot_question))
		{
			case 1:
			{
				$question = "blablabla?";
				$answerA = "blabla";
				$answerB = "blablabla";
				$answerC = "bla";
				$answerD = "what is it?";
				$answer = "D";
			}
//There are 75 cases with questions and answers
}
}
		return array ($question, $answerA, $answerB, $answerC, $answerD, $answer);
	}

And this is the quiz form:

echo "Quiz";
			echo "<br />";
			echo "<form action='?p=index&sub=register&step=checkquiz' method='post'";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='011'/>".$answerA;
			echo "<input type='radio' name='012'/>".$answerB;
			echo "<input type='radio' name='013'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
			echo "<b>".$question."</b>";
			echo "<input type='radio' name='021'/>".$answerA;
			echo "<input type='radio' name='022'/>".$answerB;
			echo "<input type='radio' name='033'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='031'/>".$answerA;
			echo "<input type='radio' name='032'/>".$answerB;
			echo "<input type='radio' name='033'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='041'/>".$answerA;
			echo "<input type='radio' name='042'/>".$answerB;
			echo "<input type='radio' name='043'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='051'/>".$answerA;
			echo "<input type='radio' name='052'/>".$answerB;
			echo "<input type='radio' name='053'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='061'/>".$answerA;
			echo "<input type='radio' name='062'/>".$answerB;
			echo "<input type='radio' name='063'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='071'/>".$answerA;
			echo "<input type='radio' name='072'/>".$answerB;
			echo "<input type='radio' name='073'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='081'/>".$answerA;
			echo "<input type='radio' name='082'/>".$answerB;
			echo "<input type='radio' name='083'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='091'/>".$answerA;
			echo "<input type='radio' name='092'/>".$answerB;
			echo "<input type='radio' name='093'/>".$answerC;
			echo "<br />";
			list ($question, $answerA, $answerB, $answerC, $answerD, $answer) = onRandomQuestionQuiz();
  			echo "<b>".$question."</b>";
  			echo "<input type='radio' name='101'/>".$answerA;
			echo "<input type='radio' name='102'/>".$answerB;
			echo "<input type='radio' name='103'/>".$answerC;
			echo "<br />";
			echo "<input type='submit' value='OK'/></form>";

Can you help me for the checker, please?

The code prints the same questions... can you help me to fix it?

You should store all your questions in an array to begin with. You should also seed the random number generator.

$questions = array(
	array(
		'question' => "blablabla?",
		'answerA' => "blabla",
		'answerB' => "blablabla",
		'answerC' => "bla",
		'answerD' => "what is it?",
		'answer' => "D"
	),
	array(
		'question' => "blablabla?",
		'answerA' => "blabla",
		'answerB' => "blablabla",
		'answerC' => "bla",
		'answerD' => "what is it?",
		'answer' => "D"
	)
	/* etc */
);

/* Generate a new random seed. The "random" sequence generated from pseudo-random generators
 * depend on the seed (how they are initialized). I believe the PHP docs say something about
 * no longer having to call mt_rands() and rands(), but at least you do in 5.3.something */
srand(time());
$qno = rand(0, count($questions));
$q = $questions[$qno];

And once you have your questions stored where you can inspect the values, checking if the given answer is correct or not shouldn't be difficult.
