Mat, did you put in a reset? reset($HTTP_POST_VARS); D.

Yes, you'll need the reset() there if you're looping through the $HTTP_POST_VARS array more than once. However: I take it that you were trying something like echo $HTTP_POST_VARS[0]; ? If so, you will indeed get the output 'array' if element 0 is an array. As someone suggested, you can use the print_r() or var_dump() functions (print_r, I think, is PHP4 only) to display it. You can also do something like ... if (is_array($HTTP_POST_VARS[0])) {

      while (list($k,$v)=each($HTTP_POST_VARS[0])) {
         echo '$HTTP_POST_VARS[0]', "[$k] = $v<br>";
      }

} else {

      echo '$HTTP_POST_VARS[0] = ', $HTTP_POST_VARS[0];

} ... In PHP3, POST/GET elements could only be one dimensional arrays, at most. In PHP4, though, these can have 2+ dimensions, so for maximum generality you'd have to have somewhat more complex code than this. -steve

Whenever I try to print something from it using print($HTTP_POST_VARS[0]); it just prints "Array". And I know it works because I've done it once and can't do it again! Am I missing something glaringly obvious? Thanks for the help, Mat PS. track_vars is ON!
