「bind_result」と「get_result」: クエリ結果の取得にはどちらの MySQLi メソッドを使用する必要がありますか?

$query1 = 'SELECT id, first_name, last_name, username FROM `table` WHERE id = ?';
$id = 5;

$stmt = $mysqli->prepare($query1);
/*
    Binds variables to prepared statement

    i    corresponding variable has type integer
    d    corresponding variable has type double
    s    corresponding variable has type string
    b    corresponding variable is a blob and will be sent in packets
*/
$stmt->bind_param('i',$id);

/* execute query */
$stmt->execute();

/* Store the result (to get properties) */
$stmt->store_result();

/* Get the number of rows */
$num_of_rows = $stmt->num_rows;

/* Bind the result to variables */
$stmt->bind_result($id, $first_name, $last_name, $username);
