PHP 클래스 yii\mongodb\Connection

Connection works together with Database and Collection to provide data access to the Mongo database. They are wrappers of the [[MongoDB PHP extension]](http://us1.php.net/manual/en/book.mongo.php). To establish a DB connection, set [[dsn]] and then call Connection::open to be true. The following example shows how to create a Connection instance and establish the DB connection: ~~~ $connection = new \yii\mongodb\Connection([ 'dsn' => $dsn, ]); $connection->open(); ~~~ After the Mongo connection is established, one can access Mongo databases and collections: ~~~ $database = $connection->getDatabase('my_mongo_db'); $collection = $database->getCollection('customer'); $collection->insert(['name' => 'John Smith', 'status' => 1]); ~~~ You can work with several different databases at the same server using this class. However, while it is unlikely your application will actually need it, the Connection class provides ability to use [[defaultDatabaseName]] as well as a shortcut method Connection::getCollection to retrieve a particular collection instance: ~~~ get collection 'customer' from default database: $collection = $connection->getCollection('customer'); get collection 'customer' from database 'mydatabase': $collection = $connection->getCollection(['mydatabase', 'customer']); ~~~ Connection is often used as an application component and configured in the application configuration like the following: ~~~ [ 'components' => [ 'mongodb' => [ 'class' => '\yii\mongodb\Connection', 'dsn' => 'mongodb://developer:password@localhost:27017/mydatabase', ], ], ] ~~~ 파일 보기 프로젝트 열기: yiisoft/yii2-mongodb 1 사용 예제들

$driverOptions		options for the MongoDB driver. Any driver-specific options not included in MongoDB connection string specification.
$dsn		host:port Correct syntax is: mongodb://[username:password@]host1[:port1][,host2[:port2:],...][/dbname] For example: mongodb://localhost:27017 mongodb://developer:password@localhost:27017 mongodb://developer:password@localhost:27017/mydatabase
$enableLogging		whether to log command and query executions. When enabled this option may reduce performance. MongoDB commands may contain large data, consuming both CPU and memory. It makes sense to disable this option in the production environment.
$enableProfiling		whether to enable profiling the commands and queries being executed. This option will have no effect in case [[enableLogging]] is disabled.
$fileStreamProtocol		name of the protocol, which should be used for the GridFS stream wrapper. Only alphanumeric values are allowed: do not use any URL special characters, such as '/', '&', ':' etc.
$fileStreamWrapperClass		name of the class, which should serve as a stream wrapper for [[fileStreamProtocol]] protocol.
$manager		MongoDB driver manager.
$options		connection options. For example: php [ 'socketTimeoutMS' => 1000, // how long a send or receive on a socket can take before timing out 'ssl' => true // initiate the connection with TLS/SSL ]
$typeMap		type map to use for BSON unserialization. Note: default type map will be automatically merged into this field, possibly overriding user-defined values.
