Making a Parameterised Query

suggest change 
$conn = sqlsrv_connect($dbServer, $connectionInfo);

$query = "SELECT * FROM [users] WHERE [name] = ? AND [password] = ?";
$params = array("joebloggs", "pa55w0rd");

$stmt = sqlsrv_query($conn, $query, $params);

If you plan on using the same query statement more than once, with different parameters, the same can be achieved with the sqlsrv_prepare() and sqlsrv_execute() functions, as shown below: 

$cart = array(
    "apple" => 3,
    "banana" => 1,
    "chocolate" => 2
);

$query = "INSERT INTO [order_items]([item], [quantity]) VALUES(?,?)";
$params = array(&$item, &$qty); //Variables as parameters must be passed by reference

$stmt = sqlsrv_prepare($conn, $query, $params);

foreach($cart as $item => $qty){
    if(sqlsrv_execute($stmt) === FALSE) {
        die(print_r(sqlsrv_errors(), true));
    }
}
