I can't get my array checkbox values in PHP

Question

I can't find out why this isn't working so please don't shred me for asking this question although it's been answered. I have a HTML array of checkboxes and I'd like to get the value of what is checked. I'm getting the questions via a cURL request.

I've tried several combinations of changing variable names, adding index values, using the

foreach ($var1 as $var1 => $value)

and still nothing.

PHP to display the questions:

      $exquest = curl_exec($ch); 
      curl_close($ch);
      $exquest = json_decode($exquest, true); 

      $numOfQuests = $exquest["questcount"]; 

      for ($i=0; $i<$numOfQuests; $i++) 
      {
      echo "<input type='checkbox' name='q[]' value='" . $exquest['question$i'] . "'> " . $exquest["question$i"] . "<br /><br />";
      }

PHP to collect checked questions:

if(is_array($_POST['q'])){
    foreach($_POST['q'] as $value){
  print_r($value);
  var_dump($value);
      }
   }

OUTPUT:

The outputs I've gotten thus far are either "Array" repeated the number of times equal to the number of boxes checked, or [0]=> 0, [1] => [1], etc but even then it only goes by total number checked not the sequence (i.e index 0, 2, and 4) it'll always come back 0,1,2 etc.

What you're getting is the expected output, What you need to change in that ? — Sulthan Allaudeen, Mar 16 '17 at 03:16
I would expect it to return the value of what's stored on the checkbox line no? Is it just my misunderstanding of checkboxes and html? I thought if you had *checkbox* > "foo", if i was checked it could return "foo" — mmorcos, Mar 16 '17 at 03:19
Yeah, I started to suspect that it wasn't stored or returning correctly from the db. It posted blank as per your suggesting which will help narrow it down. Thank you! — mmorcos, Mar 17 '17 at 00:02
Please do not add voting advice or commentary to your posts - keep them succinct and if you hang around here, and if you post good questions, you will get more upvotes than down. — halfer, Apr 05 '17 at 16:49

As @Ryan Vincent suggested, by checking var_dump($_POST); I determined that nothing was being sent from one page to the other aside form the N number of checked boxes."

Solution: I was missing the $i in q[] for name and id. Thanks all!

     echo "<input type='checkbox' name='q[$i]' id='q[$i]' value='" . $exquest["question$i"] . "'> " . $exquest["question$i"] . "<br /><br />"
