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<[email protected]> * @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!
<?php
$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);
?>
存放的数据内容:
查询所有数据:
<?php
$rows = $collection->find();
foreach ($rows as $key => $val)
{
var_dump($val);
}
?>
结果:
更改数据:
<?php
$where = array(‘title‘=>‘叶子-吴佰清‘);
$set = array(‘title‘=>‘叶子‘);
$collection->update($where,array(
‘$set‘=>$set,
));
?>
结果:
删除数据:
<?php
$collection->remove(array(
‘title‘=>‘叶子‘,
));
?>
结果:
No records is found.

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 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‘ | $db->users->update(array("b" => "q"), array(‘$inc => array("a" => 2))); |
| DELETE FROM users WHERE z="abc" | $db->users->remove(array("z" => "abc")); |
