1. Introduction to MongoDB
MongoDB (name comes from "humongous") is a scalable, high-performance, open source, schema-free, document-oriented database that integrates It combines the advantages of document databases, key-value stores, and relational databases. Official site: http://www.mongodb.org/, MongoDB features:

•Document-oriented storage (JSON-like data model is simple and powerful)
•Dynamic query
•Full index support, Extensions to internal objects and embedded arrays
• Query record analysis
• Fast, in-place updates
• Efficient storage of binary large objects (such as photos and videos)
• Replication and failover support
•Auto-Sharding supports cloud-level scalability
•MapReduce supports complex aggregation
•Business support, training and consulting

2. Install MongoDB
Installing MongoDB is very simple. You only need to download the compressed package, decompress it and run the command. Download address: http://www.mongodb. org/downloads, this article is for Windows platform, MongoDB running command: >bin/mongod. Tip: First create a folder to store data. MongoDB’s default data storage directory is /data/db/ (or c:datadb). Of course, you can also change it to a different directory by specifying the --dbpath parameter, eg:
>bin/mongod --dbpath=d:mgdatadb

3. Install MongoDB PHP extension
Download the PHP extension according to your PHP version: http://github.com/mongodb/mongo-php-driver/downloads , Tips:
1. VC6 is suitable for Apache, VC9 is suitable for IIS;
2. Thread safe is suitable for PHP running in module mode, and Non-thread safe is suitable for CGI running mode.
Modify php.ini, add: extension=php_mongo.dll, and restart the web server.

4. Examples related to PHP testing and MongoDB
1. Connect to Mongo server

Copy code The code is as follows:

//Connect to localhost:27017
$conn = new Mongo();
//Connect to the remote host default port
$conn = new Mongo('test.com');
//Connect to the remote host port 22011
$conn = new Mongo('test.com:22011');
//MongoDB has a user Name and password
$conn = new Mongo("mongodb://${username}:${password}@localhost")
//MongoDB has a username and password and specifies the database blog
$conn = new Mongo("mongodb://${username}:${password}@localhost/blog");
//Multiple servers
$conn = new Mongo("mongodb://localhost:27017,localhost :27018");
?>

Copy code The code is as follows:

< ;?php
//Connect to localhost:27017
$conn = new Mongo();
//Connect to the default port of the remote host
$conn = new Mongo('test.com');
//Connect to the remote host port 22011
$conn = new Mongo('test.com:22011');
//MongoDB has a username and password
$conn = new Mongo("mongodb:/ /${username}:${password}@localhost")
//MongoDB has a username and password and specifies the database blog
$conn = new Mongo("mongodb://${username}:${password }@localhost/blog");
//Multiple servers
$conn = new Mongo("mongodb://localhost:27017,localhost:27018");
?>

2. Specify the database and data set name (table name)

Copy the code The code is as follows:

//Select the database blog
$db = $conn->blog;
//Specify the result set (table name: users)
$collection = $db->users;
?>

Copy code The code is as follows:

//Select the database blog
$db = $conn->blog;
//Specify the result set (table name: users)
$collection = $db-> ;users;
?>

3. CRUD

Copy code The code is as follows:

//Add new
$user = array('name' => 'caleng', 'email' => 'admin@admin.com ');
$collection->insert($user);
//Modify
$newdata = array('$set' => array("email" => "test@test .com"));
$collection->update(array("name" => "caleng"), $newdata);
//Delete
$collection->remove(array ('name'=>'caleng'), array("justOne" => true));
//Find
$cursor = $collection->find();
var_dump( $cursor);
//Find one
$user = $collection->findOne(array('name' => 'caleng'), array('email'));
var_dump( $user);
?>

Copy code The code is as follows:

//Add
$user = array ('name' => 'caleng', 'email' => 'admin@admin.com');
$collection->insert($user);
//Modify
$ newdata = array('$set' => array("email" => "test@test.com"));
$collection->update(array("name" => "caleng" ), $newdata);
//Delete
$collection->remove(array('name'=>'caleng'), array("justOne" => true));
//Find
$cursor = $collection->find();
var_dump($cursor);
//Find one
$user = $collection->findOne(array(' name' => 'caleng'), array('email'));
var_dump($user);
?>

4. Close the connection

Copy code The code is as follows:

$conn->close();
?>
