私は機能を持っています:
function getROLES() {
$sql = "
SELECT wur.role_id, wur.user_id, wu.first_name, wu.last_name
FROM user_roles wur LEFT JOIN users wu ON wur.user_id = wu.user_id
WHERE wur.role_id IN (100,101)
";
try {
$db = getConnection();
$stmt = $db->query($sql);
$roles = $stmt->fetchAll(PDO::FETCH_ASSOC);
$db = null;
echo json_encode($roles);
} catch(PDOException $e) {
echo '{"error":{"text":'. $e->getMessage() .'}}';
}
}
この関数の出力は配列とJSONです
配列:
Array (
[0] => Array
( [role_id] => 100 [user_id] => 1 [first_name] => Al [last_name] => Pacino )
[1] => Array
( [role_id] => 100 [user_id] => 5 [first_name] => Brad [last_name] => Pitt )
[2] => Array
( [role_id] => 101 [user_id] => 12 [first_name] => Pierce [last_name] => Brosnan )
[3] => Array
( [role_id] => 101 [user_id] => 10 [first_name] => Johnny [last_name] => Deep )
[4] => Array
( [role_id] => 101 [user_id] => 11 [first_name] => Tom [last_name] => Hanks )
) 1
JSON:
[
{"role_id":100,"user_id":1,"first_name":"Al","last_name":"Pacino"},
{"role_id":100,"user_id":5,"first_name":"Brad","last_name":"Pitt"},
{"role_id":101,"user_id":12,"first_name":"Pierce","last_name":"Brosnan"},
{"role_id":101,"user_id":10,"first_name":"Johnny","last_name":"Deep"},
{"role_id":101,"user_id":11,"first_name":"Tom","last_name":"Hanks"}
]
問題は、すべてのユーザーのグループを特定する方法が各role_idに属していることです。次のように、出力JSONに含めるコードを変換または変更する方法:
[
{"role_id":100, "childrens":
[
{"user_id":1,"first_name":"Al","last_name":"Pacino"},
{"user_id":5,"first_name":"Brad","last_name":"Pitt"}
],
{"role_id":101, "childrens":
[
{"user_id":12,"first_name":"Pierce","last_name":"Brosnan"},
{"user_id":10,"first_name":"Johnny","last_name":"Deep"},
{"user_id":11,"first_name":"Tom","last_name":"Hanks"}
]
]
