$HTTP_POST_VARS

When information is returned from a form, it can be extracted from global variables quite easily.

However, it appears to be better to use $HTTP_POST_VARS for this. After all, this is what it was designed for.

My problem is that if values from several checkboxs are returned in an array, eg $check[], all I can get from $HTTP_POST_VARS is a variable 'check' containing the value 'Array'.

How can I extract the values from the 'check' array?

Individual items can be accessed like this:

$check[0]
$check[1]
etc.

You can loop through all like this:

while (list ($iKey, $sVal) = each ($check)) {
  // $iKey holds the indices
  // $sVal holds the values
}

Thanks, I had problems getting data out of multi-dimensional arrays.

I eventually cracked it, with a recursive routine - my original logic was a bit dodgy! I posted the script as ReadArrays.php under forms scripts.
