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

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

 * 
 * @author Wu Bai Qing<[e-mail]>
 * @version $Id: Mongodb.php 17 2011-09-17 06:04:15Z wbq $ 
*/

$mongo_server_name ='admin;
$mongo_server_pwd  ;

// 连接Mongo数据库   数据库地址:端口/账号:密码;
$mongonew 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 ->selectDB(rrs_result)selectCollection(content);
?>

数据库自动创建成功

添加一条数据!

php
$contentarray(
title=>叶子-吴佰清,
author吴佰清urlhttp://www.cnblogs.com/wubaiqing/archive/2011/09/17/2179870.html
);
insert(?>

存放的数据内容:

查询所有数据:

$rowsfind();

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

结果:

更改数据:

$where();
$set叶子);

update(=>
));
?>

结果:

删除数据:

remove(?>

结果:

No records is found.
 

完整代码:

 * Tools:
 * Zend Studio 8.x
 * Eclipse Pulg :Toggle Varpper
 * 
 * @author Wu Bai Qing<[e-mail]>
 * @version $Id: Mongodb.php 17 2011-09-17 06:04:15Z wbq $ 
);



// 添加
$content = array(
    'title'=>'叶子-吴佰清',
    'author'=>'吴佰清',
    'url'=>'http://www.cnblogs.com/wubaiqing/archive/2011/09/17/2179870.html',
);
$collection->insert($content);



// 查询
$colle = $collection->find(array('title'=>'叶子-吴佰清'));

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

// 修改
$where = array('title'=>'叶子-吴佰清');
$set = array('title'=>'叶子');

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

//删除
$collection->remove(array(
    'title'=>'叶子',1)">

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" => 1,1); padding: 5px">SELECT * FROM users WHERE age=33	$db->users->find(array("age" => 33));
$db->users->find(array("age" => 33),b FROM users WHERE age=33 ORDER BY name
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 WHERE name LIKE "%Joe%"	$db->users->find(array("name" => new MongoRegex("/Joe/")));
SELECT * FROM users WHERE name LIKE "Joe%"	$db->users->find(array("name" => new MongoRegex("/^Joe/")));
SELECT * FROM users WHERE age>33 AND age<=40	$db->users->find(array("age" => array('$gt' => 33,'$lte' => 40)));
SELECT * FROM users ORDER BY name DESC	$db->users->find()->sort(array("name" => -1));
CREATE INDEX myindexname ON users(name)	$db->users->ensureIndex(array("name" => 1));

EXPLAIN SELECT * FROM users WHERE z=3	$db->users->find(array("z" => 3))->explain()
SELECT DISTINCT last_name FROM users	$db->command(array("distinct" => "users","key" => "last_name"));
SELECT COUNT(*y) FROM users	$db->users->count();

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'
DELETE FROM users WHERE z="abc"	$db->users->remove(array("z" => "abc"));
