Yii2 redis use

To install the first extended look at the redis

composer require yiisoft/yii2-redis

Add redis configuration in the configuration file

'Components' => [
 .... 
'Redis' => [
             'class' => 'Yii \ Redis \ Connection', 
            'hostname' => yourname, 
            'password' => yourPassword, 
            'Port' => 6379, // default port configuration change where other ports 
            'Database' => 0, // used in the first few DB 
        ], 
'redis_1' => [
             'class' => 'Yii \ Redis \ Connection', 
            'hostname' => yourname, 
            'password' => yourPassword, 
            'Port' => 6379,// default port configuration change where other ports 
            'Database' =>. 1, // first few DB used 
        ], 
....
]

Instructions:

// instantiate redis 
$ redis = Yii :: $ App -> redis_1; // which redis If a cluster redis redis not configured to use other DB

String：

// set the value of a string 
$ Redis -> SET ( 'Key', 111 );
 // get the value of a string 
echo  $ Redis -> GET ( 'Key'); // 111 
// repeat SET 
$ Redis -> SET ( 'Key', 222); // 222

List：

// list 
// list data stored in 
$ Redis -> LPUSH ( 'List', 'JS' );
 $ Redis -> LPUSH ( 'List', 'Python' );
 $ Redis -> LPUSH ( 'List', 'PHP' ); 

// get all the values in the list 
$ Redis -> Lrange ( 'list', 0, -1 ); 

// added to the right side from a 
$ Redis -> RPUSH ( 'list', 'MySQL' ) ;
 $ Redis -> Lrange ( 'List', 0, -1 ); 

// from the left pop 
$ Redis -> lpop ( 'List' );
 $ Redis -> Lrange ( 'List', 0, -1 ) ; 

// from the right pop up a 
$ Redis -> RPOP ( 'list');
$redis->lrange('list', 0, -1);

HASH

// to hash table in a key set value 
// if not then set successfully, returns 1 if there will replace the original value, return 0, else return 0 
  $ Redis -> HSET ( 'hash', 'key' , 'key' );
  // get the hash of a key value of 
  $ Redis -> hget ( 'hash', 'key' );
  // get hash all of the Keys 
  $ Redis -> hkeys ( 'hash' );
  // Get all the hash values in the order of random 
  $ Redis -> hvals ( 'hash' );
  // get all the key and hash value is a sequence of random 
  $ Redis -> hgetall ( 'hash' );
  / / Get the hash key number 
  $ Redis -> hlen ( 'hash' );
 // delete a key if the hash table key is not present or absence of false returns 
  $ Redis -> HDEL ( 'hash', 'PHP');

Set: an unordered set

// add a value set in the key 
$ Redis -> Sadd ( 'key', 'value' );
 // remove the key in the set value 
$ Redis -> Srem ( 'key', 'value');

Sorted Set: an ordered collection

// add a value set in the key 
$ Redis -> Zadd ( 'key', '. 1', 'value' );
 // remove the key value in the set 
$ Redis -> zrem ( 'key', '. 1', 'value');

Note: The value of the collection will go to the weight of the list are not
