Using foreach to echo data from JSON in PHP

Basically what I have are two JSON files. One JSON file contains a set of questions and the second JSON file contains the user answers. What I want to do is echo the questions from the one json file and echo out the answers from the other inside a div.

I tried putting a foreach within a foreach. This does work to a certain extent but it echo's the questions multiple times for each answer.

<?php
$questions = "../induction.json";
$contents = file_get_contents($questions,0,null,null);
$qArray = json_decode($contents, JSON_PRETTY_PRINT);

$answers = $user."_induction.json";
$contentsA = file_get_contents($answers,0,null,null);
$qArrayA = json_decode($contentsA, JSON_PRETTY_PRINT);

?>

<div role="tabpanel" class="tab-pane fade" id="messages_with_icon_title">
<b>Quiz</b>
 <?php
    $num = 0;
    foreach($qArray as $key => $value){
       foreach($qArrayA as $key2 => $value2){
 ?>
 <form method="POST">
 <div class="row clearfix">
   <div class="col-lg-4 col-md-4 col-sm-6 col-xs-12">
     <div class="card">
        <div class="header">
            <h2><?php echo $value['question']; ?></h2>
         </div>
         <div class="body">
         <?php
             echo $value2;
         ?>
      </div>
   </div>
 </div>
</div> 
<?php   } 
} ?>
<input type="submit" class="btn btn-success waves-effect" name="submit" value="Submit" />
</form>
</div>

This is the result: https://i.sstatic.net/PX0V7.jpg

This is what the loop should look like. Note, I pulled the <form> tag out of the loop as it shouldn't have been inside.

<form method="POST">
<?php
for ($i = 0; $i < count($qArray); $i++) 
{
?>
    <div class="row clearfix">
        <div class="col-lg-4 col-md-4 col-sm-6 col-xs-12">
            <div class="card">
                <div class="header">
                    <h2><?php echo $qArray[$i]; ?></h2>
                </div> <!-- .header -->
                <div class="body">
                    <?php echo $qArrayA[$i]; ?>
                </div> <!-- .body -->
            </div> <!-- .card -->
        </div> <!-- .col-lg-4 -->
    </div> <!-- .row -->
<?php } ?>
<input type="submit" class="btn btn-success waves-effect" name="submit" value="Submit" />
</form>
