Hash operation hSet $redis->hSet('h', 'key1', 'hello'); Add element key1—>hello to the hash named h hGet $redis->hGet('h', 'key1'); Returns the value (hello) corresponding to key1 in the hash named h hL $redis->hLen('h'); Returns the number of elements in the hash named h hD $redis->hDel('h', 'key1'); Delete the domain with key1 in the hash named h hKeys $redis->hKeys('h'); Returns all keys in the hash named key hVals $redis->hVals('h') Returns the values ​​corresponding to all keys in the hash named h hGetAll $redis->hGetAll('h'); Returns all keys (fields) and their corresponding values ​​in the hash named h hExists $redis->hExists('h', 'a'); Whether there is a domain with key name a in the hash named h hIncrBy $redis->hIncrBy('h', 'x', 2); Increase the value of x in the hash named h by 2 hMset $redis->hMset('user:1', array('name' => 'Joe', 'salary' => 2000)); Add elements in batches to the hash named key hmG $redis->hmGet('h', array('field1', 'field2')); Returns the value corresponding to field1 and field2 in the hash named h redis operation related flushDB Clear current database flushAll Clear all databases randomKey Randomly returns a key in the key space $key = $redis->randomKey(); select Choose a database move Transfer a key to another database $redis->select(0); // switch to DB 0 $redis->set('x', '42'); // write 42 to x $redis->move('x', 1); // move to DB 1 $redis->select(1); // switch to DB 1 $redis->get('x'); // will return 42 rename, renameKey Rename key $redis->set('x', '42'); $redis->rename('x', 'y'); $redis->get('y'); // → 42 $redis->get('x'); // → `FALSE` renameNx Similar to remane, but if the renamed name already exists, the replacement will not succeed. setTimeout, expire Set the activity time of a key (s) $redis->setTimeout('x', 3); expireAt key survives until a unix timestamp $redis->expireAt('x', time() + 3); keys, getKeys Returns all keys that satisfy the given pattern $keyWithUserPrefix = $redis->keys('user*'); dbSize Check how many keys there are in the database now $count = $redis->dbSize(); auth Password authentication $redis->auth('foobared'); bgrewriteaof Use aof for database persistence $redis->bgrewriteaof(); slaveof Select slave server $redis->slaveof('10.0.1.7', 6379); save Synchronously save data to disk bgsave Asynchronously save data to disk lastSave Returns the Unix timestamp of the last successful save of data to disk info Returns redis version information and other details type Returns the type value of key string: Redis::REDIS_STRING set: Redis::REDIS_SET list: Redis::REDIS_LIST zset: Redis::REDIS_ZSET hash: Redis::REDIS_HASH other: Redis::REDIS_NOT_FOUND
