php操作MongoDB基礎教程（連接、新增、修改、刪除、查詢）

復制代碼 代碼如下:
//連接localhost:27017
$conn = new Mongo();

//連接遠程主機默認端口
$conn = new Mongo('test.com');

//連接遠程主機22011端口
$conn = new Mongo('test.com:22011');

//MongoDB有用戶名密碼
$conn = new Mongo("mongodb://${username}:${password}@localhost")

//MongoDB有用戶名密碼並指定數據庫blog
$conn = new Mongo("mongodb://${username}:${password}@localhost/blog");

//多個服務器
$conn = new Mongo("mongodb://localhost:27017,localhost:27018");
//選擇數據庫blog
$db = $conn->blog;
//制定結果集（表名：users）
$collection = $db->users;
//新增
$user = array('name' => 'caleng', 'email' => 'admin#admin.com');
$collection->insert($user);
//修改
$newdata = array('$set' => array("email" => "[email protected]"));
$collection->update(array("name" => "caleng"), $newdata);
//刪除
$collection->remove(array('name'=>'caleng'), array("justOne" => true));
//查找
$cursor = $collection->find();
var_dump($cursor);
//查找一條
$user = $collection->findOne(array('name' => 'caleng'), array('email'));
var_dump($user);
//關閉數據庫
$conn->close();
