sqlsrv_fetch_array() can return either NULL or FALSE. You can make your while statement as follows:

while (NULL !== ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC))) {
    if(!$row)
        break ;

    //...
}

Here's PHP function reference: http://php.net/manual/en/function.sqlsrv-fetch-array.php
