$i problem

[adi]

On the main page i have a test with multiple questions and coresponding answears. Answears to a question can be selected with checkboxes wich have the same name for a specific question (E.g. answear1[] ). Each array coresponds to a question.

When submit ,the form sends all the arrays to the processing form.
My question is how to use the $i variable outputed by a for statement into a $GET['question'] ( E.g. $GET['question$i ] !!!??? ) so i can cycle all the arrays?
Its kind of confusing but i hope you understand.
Thanks!

if all you need is "questionX" where X is a number...

$q = 'question' .$i;
echo $_GET[$q];

I wouldnt suggest making a new variable just for that when you can use:

echo $_GET['question' . $i];

How do i use it here:

for ($i=0 ;$i<$nr; $i++)
{
$var=$_GET['question'];
foreach($var as $x)
  {
   ..........

for ($i=0 ;$i<$nr; $i++) 
{ 
    $var=$_GET['answer'.$i]; 
    foreach($var as $x) 
    { 
         // x is now an array of the 'checked' checkbox 
         // values for answer $i

}
}

If multiple choice and only one answer can be selected, use radio buttons. Thay way theres no second array, just a single value for each $var above.
