sqlsrv_query considered prepared statement

Simple question I am sure.  

Is this considered a prepared statement in SQL Server in PHP?   Is this method the safest way when following the ideas of prepared statements for PHP in SQL Server?

$sql = "SELECT * FROM table.toys WHERE Id= ? or Id= ?";
$params = array(3,5);//relative to the two ? above

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