checkbox appears dynamic in php - php

Question

Here is my piece of code:
$a=mysql_query("SELECT denumire_intrebare,denumire_varianta,tip_intrebare
FROM intrebari,variante
WHERE intrebari.cod_chestionar='".$_SESSION['cod']."'
AND intrebari.cod_intrebare=variante.cod_intrebare");
while($b=mysql_fetch_array($a))
if($b['tip_intrebare']==3)
{
echo $b['denumire_intrebare'];
echo "<br>";
echo "<input type='checkbox' name='option1' value='Milk'>";
echo $b['denumire_varianta'];
echo "<br>";
}
So let me explain. I query the database and it brings me up a question and the answers that are related to it. I want the answers to put them as checkbox answers. The problem is that my question is repeating for all the answers. So if i have 5 answers then the question appears 5 times like this: question answer1, question answer2, ... . I want my question to appear only once with the answers under the question. I'm missing something but I don't know what. Any help?

Answer 1

Make an array with all $b['denumire_varianta'] and use a foreach() after the while has finished, also make your checkboxes array so you can get them afterwards:
$variante = array();
while($b=mysql_fetch_array($a)) {
if($b['tip_intrebare']==3){
$intrebare = $b['denumire_intrebare'];
$variante[] = $b['denumire_varianta'];
}
}
echo $intrebare."<br />";
foreach($variante as $varianta){
echo "<input type='checkbox' name='option[]' value='".$varianta."'>";
echo $varianta."<br />";
}
