Description:
------------
Accessing a NexusDB database from PHP using the ODBC driver results in two problems, that cannot be reproduced using any other ODBC query tools:

(1) The columns returned by odbc_fetch_array() are not indexed by their column names, but by the values!!!

(2) Getting one row with odbc_fetch_array() is fine, but as soon as you ask for the second one, the web server complains about an access violation (both Apache and IIS).

Apparently the driver does something that the ODBC library in PHP doesn't expect, but most other windows programs think is fine.

The problem exists in PHP 4.3.7 as well as PHP 5.0.0.


Reproduce code:
---------------
$db = odbc_connect("nexusdb", "", "");


// Don't use "select *", it will crash immediately.
// This is something the other ODBC tools seem to
// know and deal with as well.
//
$result = odbc_exec($db, "SELECT id, name FROM table");

$num_records_fetched  = 0;
$num_records_to_fetch = 2;

while ($row = odbc_fetch_array($result)) {
   $num_records_fetched++;
   echo "Row {$num_records_fetched}:";
   foreach ($row as $key => $value) {
      echo " {$key} => {$value}";
   }
   if ($num_records_fetched >= $num_records_to_fetch) {
      break;
   }
}


Expected result:
----------------
I'd expect to see:

row 1: id => 0001 name => foo
row 2: id => 0002 name => bar



Actual result:
--------------
I get an "access violation".


If I change "num_records_to_fetch" to 1, it no longer violates access, but I see this instead:

row 1: 0001 => 0001 foo => foo
