創建PDO實例

$dsn = 'mysql:host=localhost;dbname=test;charset=utf8';
            $username = 'username';
            $password = 'password';
$pdo = new PDO($dsn, $username, $password);

創建FPDO實例

$fPdo = new FluentPDO($pdo);

數據庫操作

查詢

$query = $fpdo->from('article')->where('id', 1);
// or shortly if you select one row by primary key
$query = $fpdo->from('user', 1);

插入

$values = array('title' => 'article 1', 'content' => 'content 1');
$query = $fpdo->insertInto('article')->values($values)->execute();
// or shortly
$query = $fpdo->insertInto('article', $values)->execute();

更新

$set = array('published_at' => new FluentLiteral('NOW()'));
$query = $fpdo->update('article')->set($set)->where('id', 1)->execute();
// or shortly if you update one row by primary key
$query = $fpdo->update('article', $set, 1)->execute();

刪除

$query = $fpdo->deleteFrom('article')->where('id', 1)->execute();
// or shortly if you delete one row by primary key
$query = $fpdo->deleteFrom('article', 1)->execute();

注意：INSERT, UPDATE and DELETE將會在->execute()之後執行

高級一點的

leftjoin

$query = $fpdo->from('article')
              ->leftJoin('user ON user.id = article.user_id')
              ->select('user.name');

如果有主鍵、外鍵等，可以簡化成

$query = $fpdo->from('article')->leftJoin('user')->select('user.name');

或者

$query = $fpdo->from('article')->select('user.name');

以上三條命令均等價於

SELECT article.*, user.name 
FROM article 
LEFT JOIN user ON user.id = article.user_id
