前端之家收集整理的这篇文章主要介绍了初识Mongodb之[CURD]-PHP版前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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

 

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 Pl
ug :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 ;

// 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:

*
* 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 $
);



// 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));
CREATE INDEX myindexname ON users(name,ts DESC) $db->users->ensureIndex(array("name" => 1,"ts" => -1));
SELECT * FROM users WHERE a=1 and b='q' $db->users->find(array("a" => 1,"b" => "q"));
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()
SELECT DISTINCT last_name FROM users $db->command(array("distinct" => "users","key" => "last_name"));
SELECT COUNT(*y) FROM users $db->users->count();
SELECT COUNT(*y) FROM users where AGE > 30 $db->users->find(array("age" => array('$gt' => 30)))->count();
SELECT COUNT(AGE) from users $db->users->find(array("age" => array('$exists' => true)))->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"));
