Use my_form_data[] in name

<form method="post" action="next.php">
  <input type="hidden" name="my_form_data" value="<?php echo htmlentities(serialize($my_arr));?>">
</form>

If I'm understanding you correctly, you can try this:

<form method="post" action="next.php">
 <input type="hidden" name="my_form_data" value="<?php echo htmlspecialchars(serialize($my_arr)) ?>">
 <button name="submit_btn">Submit</button>
</form>

Then in next.php you unserialize to get the PHP data structure back:

<?php
$my_arr = unserialize($_POST["my_form_data"]);

$hiddenvariable=array("apple","banana","cat");
foreach($hiddenvariable as $value)
{
  echo '<input type="hidden" name="my_form_data[]" value="'. $value. '">';
}

Making an array first then extracting an each elements using foreach and passing those values into hidden value.

The easiest way is to make json as string by json_encode and then decode at the time of retrieve by json_decode, 

<form method="post" action="next.php">
<input type="hidden" name="my_form_data" value="<?php echo json_encode($my_arr); ?>">
<button name="submit_btn">Submit</button>
</form>
