For some reason o'connor's code only reads one line of a csv for me... I had to replace the line 

      $data = fgetcsv($fp, 1000, $delimiter, $enclosure); //  $escape only got added in 5.3.0 

with this:

      $data;
      while (!feof($fp))
      {
        $data[] = fgetcsv($fp, 0, $delimiter, $enclosure); //  $escape only got added in 5.3.0
      }

...to get all of the data out of my string (some post data pasted into a textbox and processed only with stripslashes).
