Trying and failing to place looped content within a div - php

Question

Basically here is the scenario:
I am trying to generate a test from a database. Each test has many questions(items) each item is of a certain type (multi-choice etc), each question has multiple answers attached to it.
(I'm not looking for somebody to tell me im going about it all wrong)
I currently, loop through my query results and print out every question there. Within that loop I execute a function (present_question) for every question. Within this function is a switch case, which identifies the item type. Within each case, I run another loop to print out all the answers attached to that question.
What I am trying to do, is insert each question into a unique <div> so that I toggle the display etc between each question as they select a button for each so 1,2,3,4 etc.
However, it would appear I am struggling with this. My questions all print out, however It appears they are not within individual <divs> as I tried testing it by changing some attributes of the class and its doing nothing. :(
Here is the main code covering the whole procedure:
main loop:
//loop through every question present in query results and run function to present the different question structures
while ($qs = mysql_fetch_assoc($get_questions))
{
$type = $qs['item_type'];
$item_id = $qs['item_id'];
$question = $qs['question_text'];
echo "<div class='q_center' id='q_$q_num'>"; // insert each question into its own div
echo "<h2>Question No.$q_num </h2><br>";
echo "$question <br>"; // print out actual question
present_question($item_id, $type);
$q_num ++;
}
present_question function
function present_question($ID, $type){
// grab all the answers attached to the question
$get_answers = mysql_query("SELECT * FROM answers_tb WHERE item_id='$ID'");
echo "<form>";
// switch for different structured questions. (switched by question type)
switch ($type)
{
case "1":
multi_choice($get_answers); // just working on this type at the moment
break;
case "2":
echo "this type hasnt been done yet";
break;
}
echo "</div>";
echo "</form>";
return;
}
function for multiple choice type
function multi_choice($get_answers){
while ($answers = mysql_fetch_assoc($get_answers))
{
$as = $answers['text_value'];
echo "<input type='radio' name='1' value='$as'>$as<hr />";
}
return;
}
hopefully you guys can help me.
I am a beginner, so I do apologise if my code is an abomination :D
thanks,

Answer 1

rough version (untested)
$i = 0; //declares the counter $i
//loop through every question present in query results and run function to present the different question structures
while ($qs = mysql_fetch_assoc($get_questions))
{
$type = $qs['item_type'];
$item_id = $qs['item_id'];
$question = $qs['question_text'];
$i++; // adds 1 to $i
echo "<div class='q_center' id='q_$q_num'>"; // insert each question into its own div
echo "<h2>Question No.$q_num </h2><br>";
echo "<div class=question" .$i. ">"; //appends $i to the div name creating question[$i]
echo "$question <br>"; // print out actual question
echo "</div>";
present_question($item_id, $type);
$q_num ++;
}
should make div's named question1, question2, etc
