Help with PHP guess the object game

[sunaina]

This is the first program I am writing using PHP and Mysql. I am
creating a game where user thinks of an object and my program
guesses the object while asking series of yes/no questions. All a
user has to do is say yes or no to the questions that my program
asks. I have coded until the part where once user thinks of an
object and enters submit and the program asks him the first
question. Now when the user enters yes/no for this first quesiton I
want to display the same form again but with next question. I know
which question to ask but don't know two things:

1. how to make the same form appear again with different question.
In the form action I have tried calling the same form again and also
tried using PHP_SELF but both doesnot seem to work.

2. how to store the previously asked question in an array that can be
read later in the program when the next question is asked.

So far, have been able to display the same form again using PHP_SELF
function but not able to read and display the next question onto the
same form. My first html form calls the second form, when user hits
submit. My code looks like this for second form:

<?php
$db = mysql_connect(" localhost", "root", "mmmm") or
die(mysql_error ());
mysql_select_db ("guess") or die(mysql_error ());

// Find out all questions and answers which have
// already been asked

$i=0;
$asked_question s = array();
$asked_answers = array();
$num_questions = 0;

if (isset($_POST["prev_quest ion"])) {
$asked_question s[$i] = $_POST["prev_quest ion"];
$asked_answers[$i] = $_POST["prev_answe r"];
$num_questions = $i++;
echo "Asked Ques Array = $num_questions< br>";
}

//finds possible questions still left that are not in asked questions
array
$possible_quest ions = array();
$questions_sum = array();
$i = 0;
while ($row = mysql_fetch_ass oc($result)) {
extract($row);
$possible_quest ions[$i] = $qid;
$questions_sum[$i] = $sum;
print_r($qid . " " . $sum . "<br>");
$i++;
}
$num_possible_q uestions = $i;
$ideal_sum = $num_objs / 2;
$question_to_as k_index = 0;
for ($i=0; $i<$num_possibl e_questions; $i++) {
$question_to_as k_index = $i;
if ($questions_sum[$i] < $ideal_sum)
break;
}
$question_to_as k = $possible_quest ions[$question_to_as k_index];

// do query in database to find the question to be asked
$question_query = "select question from question
where(id=$quest ion_to_ask)";
$current_questi on=mysql_query( $question_query , $db);
while ($row = mysql_fetch_ass oc ($current_quest ion)){
extract ($row);
echo "<br>QUESTI ON = $question<br><b r>";
unset($possible _questions[$question_to_as k]);
}

if (isset($_POST['YES']) || ($_POST['NO'])) {
$prev_question = $question;

if(isset($_POST['YES'])){
$prev_answer = 1;
echo "Q=$prev_questi on";
echo "A=$prev_answer ";

} else if(isset($_POST['NO'])) {
$prev_answer=0;
echo "Q=$prev_questi on";
echo "A=$prev_answer ";
}
}
?>
<form method="POST" action="<?php echo $PHP_SELF; ?>">
<input type="image" alt="Theimage" src="C:\Program Files\Modem
Helper\Pictures \wink.gif">
<input type="submit" name="YES" value="YES">
<input type="submit" name="NO" value="NO">
<input type="hidden" name="prev_ques tion" value="<?php echo
$prev_question; ?>">
<input type="hidden" name="prev_answ er" value="<?php echo
$prev_answer;?> ">
<input type="hidden" name="question_ to_ask" value="<?php echo
$question_to_as k;?>">
<input type="hidden" name="$num_aske d_ques" value="<?php echo
$num_asked_ques ;?>">
</form>
?>

What I am trying to do here is once current question is asked, puts
current question in asked question array, deletes current question
from possible questions array, and displays next current question from
possible questions array. For some reason my program is not doing the
above mentioned steps. Serious help reqd.
