初识Mongodb之[CURD]-PHP版

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  = '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 StatementMongo Query Language StatementCREATE 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"));
