SDK for PHP で情報の取得や更新

以下のサンプルコードでは、Facebook SDK for PHP を利用して、ID,パスワードで Facebookへログインし、ログインユーザーの名前を取得したり、ウォールへの書き込みを行ったり、写真をアルバムへアップロードしたりするコードです。

SDK for PHP でユーザー名取得(アルファベット)

SDK for PHP を介して、ユーザーのプロファイルを取得し、そのユーザー名を表示させます。

以下のサンプルコードの下記3つの内容を自分の環境に合わせて書き換えて下さい。

YOUR_PHP_SDK_DIR_PATH(php-sdkへのパス)
YOUR_APP_ID (FacebookアプリケーションのID)
YOUR_APP_SECRET (FacebookアプリケーションのSECRET)

FacebookアプリケーションIDなどが不明な場合は一度こちらのページを読んで下さい。php-sdkの設置やFacebookアプリケーションの作成など一通り説明されています。

Graph API Methods

グラフ(Graph)APIメソッドを呼び出すには、最初のパラメータ、および必要に応じて他のオプションのパラメータとして取得したいエンドポイントのパスを渡します。

$ret = $facebook->api($path, $method, $params);

path
要求に対するグラフAPIのパス例えば “/me/”の場合、ログインユーザーのプロフィールに記録されます。

method
[オプション] 要求内容に応じてHTTPメソッドを指定します。’GET’, ‘POST’, あるいは ‘DELETE’　を指定。

params
[オプション] 特定のグラフ(Graph)APIでは、固有のパラメーターを指定することが出来ます。パラメーターは「’名前’ => ‘値’」のペアにして連想配列として指定します。

FQLクエリ(Queries)

FQLクエリを実行するには、メソッドに ‘fql.query’ と指定し、’query’ SQLを指定します。それらのパラメータを配列として渡します。

<!-- サンプルコード -->
$ret = $facebook->api( array(
                         'method' => 'fql.query',
                         'query' => 'SELECT . . . ',
