Available since version2.0
Source Code https://github.com/yiisoft/yii2-redis/blob/master/Connection.php

The redis connection class is used to establish a connection to a redis server.

By default it assumes there is a redis server running on localhost at port 6379 and uses the database number 0.

It is possible to connect to a redis server using $hostname and $port or using a $unixSocket.

It also supports the AUTH command of redis. When the server needs authentication, you can set the $password property to authenticate with the server after connect.

The execution of redis commands is possible with via executeCommand().

$retries public property (available since version 2.0.7)

$socket public property
public resource|false $socket null
$socketClientFlags public property (available since version 2.0.5)

Bitmask field which may be set to any combination of connection flags passed to stream_socket_client(). Currently the select of connection flags is limited to STREAM_CLIENT_CONNECT (default), STREAM_CLIENT_ASYNC_CONNECT and STREAM_CLIENT_PERSISTENT.

Warning: STREAM_CLIENT_PERSISTENT will make PHP reuse connections to the same server. If you are using multiple connection objects to refer to different redis databases on the same $port, redis commands may get executed on the wrong database. STREAM_CLIENT_PERSISTENT is only safe to use if you use only one database.

You may still use persistent connections in this case when disambiguating ports as described in a comment on the PHP manual e.g. on the connection used for session storage, specify the port as:

'port' => '6379/session'

See also https://www.php.net/manual/en/function.stream-socket-client.php.

public integer $socketClientFlags STREAM_CLIENT_CONNECT
$unixSocket public property (available since version 2.0.1)
