导读:需要搭建好Mangodb的环境,没有搭建好的请看下:初识Mongodb总结
边看边操作,这样才能记得牢,实践是检验真理的唯一标准.
光看不练假把式,光练不看傻把式,边看边练真把式.
知识改变命运,为了我们的未来,为了我们的梦想,一起动起来吧!

开发环境

操作系统 : Mac Os X
集成环境 : Mamp
编程语言 : PHP
Server : Mongodb
Extension : Mongo-1.2.4
管理工具 : Rock-PHP
学习资源 : http://www.php.net/manual/en/book.mongo.php

行动

在了实践之前,希望大家看一下上面的学习资源,了解一下基本操作.
数据连接初始账号密码
账号:admin
密码:admin
首先我们建立一个文件:mongodb.php,设置需要连接账号密码,连接数据库
* @version $Id: Mongodb.php 17 2011-09-17 06:04:15Z wbq $ */ $mongo_server_name = 'admin'; $mongo_server_pwd = 'admin'; // 连接Mongo数据库 数据库地址:端口/账号:密码; $mongo = new Mongo('mongodb://localhost:27017/admin:admin'); // 选择一个数据库和要操作的集(如果没有数据库默认创建) $collection = $mongo->selectDB('rrs_result')->selectCollection('content'); ?>
数据库自动创建成功

添加一条数据!
'叶子-吴佰清', 'author'=>'吴佰清', 'url'=>'http://www.cnblogs.com/wubaiqing/archive/2011/09/17/2179870.html', ); $collection->insert($content); ?>
存放的数据内容:

查询所有数据:
find(); foreach ($rows as $key => $val) { var_dump($val); } ?>
结果:

更改数据:
'叶子-吴佰清'); $set = array('title'=>'叶子'); $collection->update($where,array( '$set'=>$set, )); ?>
结果:

下面是sql和Mongodb对应的一些语法:

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));
SELECT a,b FROM users $db->users->find(array(), array("a" => 1, "b" => 1));
SELECT * FROM users WHERE age=33 $db->users->find(array("age" => 33));
SELECT a,b FROM users WHERE age=33 $db->users->find(array("age" => 33), array("a" => 1, "b" => 1));
SELECT a,b FROM users WHERE age=33 $db->users->find(array("age" => 33), array("a" => 1, "b" => 1));
SELECT a,b FROM users WHERE age=33 ORDER BY name $db->users->find(array("age" => 33), array("a" => 1, "b" => 1))->sort(array("name" => 1));
SELECT * FROM users WHERE age>33 $db->users->find(array("age" => array('$gt' => 33)));
SELECT * FROM users WHERE age<33 $db->users->find(array("age" => array('$lt' => 33)));

SELECT * FROM users ORDER BY name DESC $db->users->find()->sort(array("name" => -1));
CREATE INDEX myindexname _disibledevent=>$db->users->ensureIndex(array("name" => 1));

SELECT * FROM users LIMIT 10 SKIP 20 $db->users->find()->limit(10)->skip(20);
SELECT * FROM users WHERE a=1 or b=2 $db->users->find(array('$or' => array(array("a" => 1), array("b" => 2))));
SELECT * FROM users LIMIT 1 $db->users->find()->limit(1);
EXPLAIN SELECT * FROM users WHERE z=3 $db->users->find(array("z" => 3))->explain()

UPDATE users SET a=1 WHERE b='q' $db->users->update(array("b" => "q"), array('$set' => array("a" => 1)));
UPDATE users SET a=a+2 WHERE b='q' $db->users->update(array("b" => "q"), array('$inc => array("a" => 2)));
DELETE FROM users WHERE z="abc" $db->users->remove(array("z" => "abc"));
