title: PHP: accessing sequentially numbered POST entries
body: <p>I'm going to have html form that is going to send out chunks of text labeled 'chunk1', 'chunk2', 'chunk3' up to a potentially unknown number. Is there a way to sequentially go through $_POST['chunk1'] and so on until one isn't set?
  I could do a foreach but the foreach is going to contain other POST values too.</p>
