Homephp教程php手册一个最简的Thinkphp3.2 操作Mongodb的例子

看到Thinkphp网站上没有调用Mongodb的例子,就写一个一个最简的Thinkphp操作Mongodb的例子。欢迎讨论
【前提】
Thinkphp对Mongdb的支持依赖于PHP对Mongodb的支持。这是前提。如果出现类似“系统不支持:mongoClient”的提示,说明你的PHP还没支持Mongodb。

那么你需要做的就是
1、去https://github.com/mongodb/mongo-php-driver/downloads下载最新的PHP-Mongodb扩展包,下载后把和你PHP大版本相符合的文件重命名为php_mongo.dll
如,我的PHP是5.3.13,win7 64位系统,那么就把
php_mongo-1.3.2RC1-5.3-vc9-x86_64.dll改成php_mongo.dll
2、把改名后的文件复制到php的ext文件夹
3、修改php.ini ,增加 extension=php_mongo.dll



【配置】
修改配置文件如下,即可链接mongodb数据库:<?php <br /> return array(<br>     //'配置项'=>'配置值'<br>     'DB_TYPE' => 'mongo', // 数据库类型<br>     'DB_HOST' => 'localhost', // 服务器地址<br>     'DB_NAME' => 'local', // 数据库名<br>     'DB_USER' => '', // 用户名<br>     'DB_PWD' => '', // 密码<br>     'DB_PORT' => '27017', // 端口<br>  );【代码】
对于操作mongodb,要使用M方法。
因此要初始化一个类。假设数据库里有数据表user,那么要给user创建一个继承自MongoModel的模型:<?php <br /> namespace Home\Model;<br> use Think\Model\MongoModel;<br> Class UserModel extends MongoModel <br> {       <br>  //可以是空的。<br> }修改IndexController如下,即可调用Mongodb中local数据库里的user Collection<?php <br />  namespace Home\Controller;<br> use Think\Controller;<br> class IndexController extends Controller {<br>     public function index(){<br>      $Model =  D("User");<br>     $Model->create();<br>      $Model->name = '流年2';<br>     $Model->add();<br>      $a = $Model->select();<br>      var_dump($a);<br>  <br>     }<br> }
