導讀:需要搭建好Mangodb的環境,沒有搭建好的請看下:初識Mongodb總結

邊看邊操作,這樣才能記得牢,實踐是檢驗真理的唯一標準.

光看不練假把式,光練不看傻把式,邊看邊練真把式.

知識改變命運,為了我們的未來,為了我們的夢想,一起動起來吧!

開發環境

操作系統　　: Mac Os X

集成環境　　: Mamp

編程語言　　: PHP

Server　　 : Mongodb

Extension : Mongo-1.2.4

管理工具　　: Rock-PHP

學習資源　　: http://www.php.net/manual/en/book.mongo.php

行動

在了實踐之前,希望大家看一下上面的學習資源,了解一下基本操作.

數據連接初始賬號密碼

賬號:admin

密碼:admin

首先我們建立一個文件:mongodb.php,設置需要連接賬號密碼,連接數據庫

<?php
/**
 * Mongodb Test
 * 
 * Tools:
 * Zend Studio 8.x
 * Eclipse Plug :Toggle Varpper

 * 
 * @author Wu Bai Qing<wbqyyicx@gmail.com>
 * @version $Id: Mongodb.php 17 2011-09-17 06:04:15Z wbq $ 
 */

$mongo_server_name = 'admin';
$mongo_server_pwd  = 'admin';

// 連接Mongo數據庫   數據庫地址:端口/賬號:密碼;
$mongo = new Mongo('mongodb://localhost:27017/admin:admin');

// 選擇一個數據庫和要操作的集(如果沒有數據庫默認創建)
$collection = $mongo->selectDB('rrs_result')->selectCollection('content');
?>

數據庫自動創建成功

添加一條數據!

<?php
$content = array(
    'title'=>'葉子-吳佰清',
    'author'=>'吳佰清',
    'url'=>'http://www.rzrgm.cn/wubaiqing/archive/2011/09/17/2179870.html',
);
$collection->insert($content);
?>

存放的數據內容:

查詢所有數據:

<?php
$rows = $collection->find();

foreach ($rows as $key => $val)
{
    var_dump($val);
}
?>

結果:

更改數據:

<?php
$where = array('title'=>'葉子-吳佰清');
$set = array('title'=>'葉子');

$collection->update($where,array(
    '$set'=>$set,
));
?>

結果:

刪除數據:

<?php
$collection->remove(array(
    'title'=>'葉子',
));
?>

結果:

No records is found.

完整代碼:

<?php
/**
 * Mongodb Test
 * 
 * Tools:
 * Zend Studio 8.x
 * Eclipse Pulg :Toggle Varpper
 * 
 * @author Wu Bai Qing<wbqyyicx@gmail.com>
 * @version $Id: Mongodb.php 17 2011-09-17 06:04:15Z wbq $ 
 */

$mongo_server_name = 'admin';
$mongo_server_pwd  = 'admin';

// 連接Mongo數據庫   數據庫地址:端口/賬號:密碼;
$mongo = new Mongo('mongodb://localhost:27017/admin:admin');

// 選擇一個數據庫和要操作的集(如果沒有數據庫默認創建)
$collection = $mongo->selectDB('rrs_result')->selectCollection('content');


/*
// 添加
$content = array(
    'title'=>'葉子-吳佰清',
    'author'=>'吳佰清',
    'url'=>'http://www.rzrgm.cn/wubaiqing/archive/2011/09/17/2179870.html',
);
$collection->insert($content);
*/

/*
// 查詢
$colle = $collection->find(array('title'=>'葉子-吳佰清'));

foreach ($colle as $key => $val)
{
    var_dump($val);
}
*/

/*
// 修改
$where = array('title'=>'葉子-吳佰清');
$set = array('title'=>'葉子');

$collection->update($where,array(
    '$set'=>$set,
));
*/

/*
//刪除
$collection->remove(array(
    'title'=>'葉子',
));
*/

下面是sql和Mongodb對應的一些語法:

SQL Statement	Mongo Query Language Statement
CREATE TABLE USERS (a Number, b Number)	Implicit or use MongoDB::createCollection().
INSERT INTO USERS VALUES(1,1)	$db->users->insert(array("a" => 1, "b" => 1));
