Description:
------------
The same problem as fixed in bug #68298 for oci_bind_by_name exists in oci_bind_array_by_name as well. I have a tested patch and will submit it soon™.

Test script:
---------------
$sql = '
  BEGIN
      SELECT -1 BULK COLLECT INTO :a FROM DUAL;
  END;
';

$stmt = oci_parse($conn, $sql);

oci_bind_array_by_name($stmt, ':a', $a, 5000, 10, SQLT_INT);

oci_execute($stmt);

var_dump($a);

Expected result:
----------------
Array
(
    [0] => -1
)

Actual result:
--------------
Array
(
    [0] => 4294967295
)
