For the below query:
----------
$res = mysql_query("select * from tableOne where clientID='".
$_GET['getClientId']."'") or die(mysql_error());
if($inf = mysql_fetch_array($res)
-----------------
The return from this ($inf = mysql_fetch_array($res) looks like this:
$inf["firstname"]
$inf["lastname"]
$inf["address"]
I assume this translates to?
0 = firstname
1 = lastname
3 = address
