<?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");
-
//选择数据库blog
-
$db = $conn->blog;

-
$collection = $db->users;

$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);
