Description:
------------
In sqlsrv_query function, fourth parameter is array that can contain following three options with corresponding keys :  QueryTimeout, SendStreamParamsAtExec	, Scrollable

You would assume that you can specify options in any order, however, this is not true.

If you run following script, you will hit unspecified error "[Microsoft][ODBC Driver Manager] Invalid cursor state"

However, if you change order to:
$config = array(
    'Scrollable'    => SQLSRV_CURSOR_KEYSET,
    'QueryTimeout'  => 2,
);

then everything works OK.

As this is illogical, I think this is bug and should be fixed.


Test script:
---------------
$link = sqlsrv_connect ( 'serverName\sqlexpress', $connectionInfo );

$config = array(
    'QueryTimeout'  => 2,
    'Scrollable'    => SQLSRV_CURSOR_KEYSET,
);

$query  = "CREATE TABLE #MY_TABLE([var1] [bigint] NOT NULL);";
$result = sqlsrv_query($link,$query,array(),$config) or die("ERROR ". print_r(sqlsrv_errors(),true));


Expected result:
----------------
OK

Actual result:
--------------
ERROR Array ( [0] => Array ( [0] => 24000 [SQLSTATE] => 24000 [1] => 0 [code] => 0 [2] => [Microsoft][ODBC Driver Manager] Invalid cursor state [message] => [Microsoft][ODBC Driver Manager] Invalid cursor state ) )
