1、连接Mongo服务器
- <?php
- //连接localhost:27017
- $conn = new Mongo();
- //连接远程主机默认端口
- $conn = new Mongo(‘test.com’);
- //连接远程主机22011端口
- $conn = new Mongo(‘test.com:22011′);
- //MongoDB有用户名密码
- $conn = new Mongo(“mongodb://${username}:${password}@localhost”)
- //MongoDB有用户名密码并指定数据库blog
- $conn = new Mongo(“mongodb://${username}:${password}@localhost/blog”);
- //多个服务器
- $conn = new Mongo(“mongodb://localhost:27017,localhost:27018″);
- ?>
2、指定数据库和数据集名（表名）
- <?php
- //选择数据库blog
- $db = $conn->blog;
- //制定结果集（表名：users）
- $collection = $db->users;
- ?>
3、CRUD
- <?php
- //新增
- $user = array(‘name’ => ‘caleng’, ‘email’ => ‘admin@admin.com’);
- $collection->insert($user);
- //修改
- $newdata = array(‘$set’ => array(“email” => “test@test.com”));
- $collection->update(array(“name” => “caleng”), $newdata);
- //删除
- $collection->remove(array(‘name’=>‘caleng’), array(“justOne” => true));
- //查找
- $cursor = $collection->find();
- var_dump($cursor);
- //查找一条
- $user = $collection->findOne(array(‘name’ => ‘caleng’), array(‘email’));
- var_dump($user);
- ?>
4、关闭连接
- <?php
- $conn->close();
- ?>
