Question

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.

Answer 1

how about:

for ( $i=1 ; isset($_POST['chunk'.$i]) ; $i++) {
  // Do your stuff
}
