The populating of a listbox is pretty easy - just loop through the array
and echo the appropriate data, i.e.
foreach ($myArray as $myItem)
echo "<option value='$myItem'>$myItem</option>\n";
Of course, if you have a unique identifier for each item, that would go
in the value field instead of the item itself - but it gets the point
across.
If you want to display something based on the selection, you'll need a
client side language such as javascript; the best way to do it would be
to use AJAX to fetch the data from the server. See comp.lang.javascript
for more information on javascript and AJAX.
