Actually, if you make the names in the form resemble array variables,
this can be greatly simplified.

Something similar to the following might be what you are looking for:
<input type="text" name="item[0]">
<input type="text" name="item[1]">

when the form is passed to the next script, there will be a single 
variable called $item - and it will be an array with two values. 
This is one of the neater features of PHP... I would recommend generating 
the input fields using something like the following:

for ($loop=0; $loop < $num_needed; $loop++) {
  echo "<input type=\"text\" name=\"item[$loop]\"><br>";

in the result script you can then traverse the passed array $item 
with a foreach loop (if you are using PHP4). Something like the following 
could possibly work.

foreach($item as $key=>$value) {
echo "Index #$key = $value<br>";
