Operating MongoDB database with PHP_PHP tutorial

PHP operates MongoDB database

1. Introduction to MongoDB

MongoDB (the name comes from "humongous") is a scalable, high-performance, open source, schema-free, document-oriented database that combines the advantages of document databases, key-value storage and relational databases.

MongoDB features:

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

2. Install MongoDB

Installing MongoDB is very simple, just download the compressed package, decompress it and run the command

Download address: https://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.

Example: >bin/mongod –dbpath=d:mgdatadb

For more information, please refer to my CSDN blog: MongoDB installation configuration

3. Install MongoDB PHP extension

Download the PHP extension according to your PHP version:

http://php.net/manual/en/mongo.installation.php#mongo.installation.nix http://www.php.net/manual/en/mongo.installation.php#mongo.installation.windows

Tips: 1. VC6 is suitable for Apache and 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.

Ubuntu installation steps:

1. Download the plug-in: mongo-php-driver

2. Unzip and install:

$ tar zxvf mongodb-mongodb-php-driver- .tar.gz $ cd mongodb-mongodb-php-driver- $ phpize $ ./configure $ make all $ sudo make install 3. Configure php.ini

#extension=uploadprogress.so #extension=http.so #extension=intl.so #extension=curl.so

extension=/usr/lib/php5/20121212/curl.so extension=/usr/lib/php5/20121212/gd.so extension=/usr/lib/php5/20121212/json.so extension=/usr/lib/php5/20121212/mysql.so extension=/usr/lib/php5/20121212/mysqli.so #extension=/usr/lib/php5/20121212/opcache.so extension=/usr/lib/php5/20121212/pdo.so extension=/usr/lib/php5/20121212/pdo_mysql.so #extension=/usr/lib/php5/20121212/readline.so #extension=/usr/lib/php5/20121212/xdebug.so extension=/usr/local/lib/php/extensions/no-debug-non-zts-20121212/redis.so extension=/usr/local/lib/php/extensions/no-debug-non-zts-20121212/mongo.so

4. Restart apache

sudo /etc/init.d/apache2 restart

5. Modify the default startup items (optional)

sudo vim /etc/apache2/apache2.conf

Add the configuration code as follows:

1234567891011121314 * : 80 > ServerAdmin webmaster@localhost DocumentRoot / home / homer / workspace / home / homer / workspace / money_client> DirectoryIndex index.html index.php Options Indexes FollowSymLinks AllowOverride None Require all granted cf31c056bf49ba7331f03f0e8957fb2c ServerName localhost DirectoryIndex index.html index.php ErrorLog ${APACHE_LOG_DIR} / error_alibuyer.log CustomLog ${APACHE_LOG_DIR} / access_alibuyer.log combined 211cd967736d80f43a4249b96cada09f

4. PHP example

1. Connect to Mongo server

1234567891011121314 $conn = new Mongo(); // 连接localhost:27017 $conn = new Mongo( 'test.com' ); // 连接远程主机默认端口 $conn = new Mongo( 'test.com:22011' ); //连接远程主机22011端口 // MongoDB有用户名密码 $conn = new Mongo( mongodb://${username}:${password}@localhost ); // MongoDB有用户名密码并指定数据库blog $conn = new Mongo( mongodb://${username}:${password}@localhost/blog ); // 多个服务器 $conn = new Mongo( mongodb://localhost:27017,localhost:27018 ); ?> Or use MongoClient()

1234567891011121314151617 $MONGO_SERVER = array ( 'host' => '10.123.55.16' , 'port' =>27017, 'dbname' => 'mimvp_money' , 'user' => '' , 'pwd' => '' ); $count = $coll -> count (); print ( count: . $count ); $host_port = $MONGO_SERVER [ 'host' ] . : . $MONGO_SERVER [ 'port' ]; // '10.123.55.16:20517' $conn = new MongoClient( $host_port ); $db = $conn ->selectDB( $MONGO_SERVER [ 'dbname' ]); $coll = new MongoCollection( $db , $connName ); $conn ->close(); ?>

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

1234 $db = $conn ->blog; // 选择数据库blog $collection = $db ->users; // 制定结果集（表名：users） ?>

3. CRUD operation

123456789101112131415 $user = array ( 'name' => 'caleng' , 'email' => '[email protected]' ); // 新增 $collection ->insert( $user ); $newdata = array ( '$set' => array ( email => [email protected] )); // 修改 $collection ->update( array ( name => caleng ), $newdata ); $collection ->remove( array ( 'name' => 'caleng' ), array ( justOne => true)); // 删除 $cursor = $collection ->find(); // 查找 var_dump( $cursor ); $user = $collection ->findOne( array ( 'name' => 'caleng' ), array ( 'email' )); // 查找一条 var_dump( $user ); ?>

4. Close the connection

123 $conn ->close(); ?>

5. Sample code

123456789101112131415161718192021222324252627282930313233343536373839 //这里采用默认连接本机的27017端口，当然你也可以连接远程主机如192.168.0.4:27017,如果端口是27017，端口可以省略 $m = new Mongo(); // 选择comedy数据库，如果以前没该数据库会自动创建，也可以用$m->selectDB(comedy); $db = $m ->comedy; //选择comedy里面的collection集合，相当于RDBMS里面的表，也-可以使用 $collection = $db ->collection; $db ->selectCollection( collection ); //添加一个元素 $obj = array ( title => Calvin and Hobbes- . date ( 'i:s' ), author => Bill Watterson ); //将$obj 添加到$collection 集合中 $collection ->insert( $obj ); //添加另一个元素 $obj = array ( title => XKCD- . date ( 'i:s' ), online => true ); $collection ->insert( $obj ); //查询所有的记录 $cursor = $collection ->find(); //遍历所有集合中的文档 foreach ( $cursor as $obj ) { echo $obj [ title ] . ; } //删除所有数据 //$collection->remove(); //删除 name 为hm //$collection->remove(array('name'=>'hm')); //断开MongoDB连接 $m ->close(); ?>
