II. yii2 soft comes with mongodb and installs the append composer.

Composer require -- prefer-dist yiisoft/yii2-mongodb

/Vendor/yiisoft/yii2-mongodb introduced mongodb

3. Use crud

Config/web. php

'Mongodb '=> [
'Class' => '\ yii \ mongodb \ connection ',
'Dsn '=> 'mongodb: // tank: test@192.168.33.10: 27017/admin ',
],

Use yii \ mongodb \ Query;
 
Public function actionIndex ()
{
 
$ Query = new Query;
// Compose the query
$ Query-> select (['_ id', 'sex'])
-> From ('admin ')
-> Limit (10 );
// Execute the query
$ Rows = $ query-> all ();
 
Print_r ($ rows );
 
// Return $ this-> render ('index ');
}



Use mongodb extension in Yii Framework

Prerequisites: The mongodb database is installed.

Install the php driver of mongo

Download the mongo extension of Yii:

This is version 1.3.6 of YiiMongoDbSuite.
PHP Mongo driver version 1.0.5 or earlier

Download link: http://pan.baidu.com/s/1jGuWP1O

Other versions Download link: https://github.com/canni/YiiMongoDbSuite

File: YiiMongoDbSuite.tar.gz

Decompress the package and place the file under the/protected/extensions folder of the application.

Make sure that the folder name is YiiMongoDbSuite.

Configure application

Vi/protected/config/main. php



'Import' => array (
...
'Ext. YiiMongoDbSuite. * ', // plug-in root directory file
),

'Components' => array (
...
'Mongodb '=> array (
'Class' => 'ongodb', // master file
'Connectionstring' => 'mongodb: // 127.0.0.1: 8080', // server address
'Dbname' => 'mydatabasename ', // database name
'Fsyncflag' => true, // mongodb ensures that all data written to the database is stored securely to the disk.
'Safeflag' => true, // The status of all write operations that mongodb is waiting to retrieve, and check
'Usecursor '=> false, // if it is set to true, the cursor is enabled.
),
),

In this way, the configuration is complete. Of course, make sure that your mongodb is installed locally and the port number is configured on port 27107 before it can be connected.

Test the Model below:

Put the following code in/protected/models/User. php:

Class User extends EMongoDocument
{
Public $ login;
Public $ name;
Public $ pass;

// This has to be defined in every model, this is same as with standard Yii ActiveRecord
Public static function model ($ className =__ CLASS __)
  {
Return parent: model ($ className );
  }

// This method is required!
Public function getCollectionName ()
  {
Return 'users ';
  }

Public function rules ()
  {
Return array (
Array ('login, pass', 'required '),
Array ('login, pass', 'length', 'Max' => 20 ),
Array ('name', 'length', 'Max' => 255 ),
);
  }

Public function attributeLabels ()
  {
Return array (
'Login' => 'User login ',
'Name' => 'Full name ',
'Pass' => 'password ',
);
  }
}

Test it in the controller.

$ Users = User: model ()-> findAll ();
Var_dump ($ users );

If no error is reported, it indicates that it can be used normally.
