500 Internal server error while running sqlsrv_query in PHP

Question

Hello everyone I am having a problem with sqlsrv_query I will be grateful to you please provide some help.
I am running a query through php:
$ls_parcel_query = "select  * from  ParcelDetail order by ExtractDate";
$result = sqlsrv_query($conn, $ls_parcel_query, array(), array("Scrollable"=>"keyset","QueryTimeout"=>300));
$no_of_rows = sqlsrv_num_rows($result);
echo "<br/>".$no_of_rows;
It gives (After 30 seconds):
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
I have php.ini settings like below:
max_execution_time = 90
memory_limit = 128M
While running this query in SQL SERVER 2008 R2, it successfully gives result in some times in 1 minute and sometimes in 2 minutes.
