How can I push three arrays of the ticked checkboxes to PHP?

I have a table with dynamic data from the db and when the user ticks the checkboxes I want to submit three arrays of the ticked checkboxes that contain different data: [Dev_Id], [dev_comment], [manuf_comment].

This is what I am currently doing but its not ok because when I submit i cant access all three arrays:

<td>
   <input type="checkbox" name="devices[<?php echo $cases["dev_comment"]; ?>][<?php echo $cases["manuf_comment"]; ?>]" value="<?php echo $cases["Dev_Id"] ?>">
</td>

In PHP:

if (isset($_POST['save_comments']) && is_array($_POST['manuf_comment'])) {
  ///    
}

Any suggestions?
