[Email protected] ~]# tar xzf redis-3.0.2].tar.gz
[Email protected] ~]# CD redis-3.0.2
[[email protected] redis-3.0.2] #ls
[[email protected] redis-3.0.2] #make
Compilation succeeded:
To start and run Redis:

Detailed

A) Connect to Redis server:

• Connect: Connecting to server
• Pconnect: Long Connection
• AUTH: Permission Validation
• Select: Choose DB
• Close: Closing the connection
• setOption: Set client options
• GetOption: Get Client options
• ping:ping Redis Server
• Echo: Output string

Note that if you operate redis frequently, and the connect and close will be very expensive, it is recommended to use Pconnect to establish a long connection.

b) string read and write function

• Append : Append a value after a value
• DECR : decrements the value of a key
• INCR: Increments the value of a key
  
• get : Get a value
• Set: Sets a value
• Getset : Sets the value and returns the old value
• mGet : Bulk Fetch values
• mSet : Batch setting values
• strlen : Get value length

Note: If you can use bulk operations as much as possible, reduce the frequent connection to Redis database performance

c) hash read and write function

• Hdel : Delete a multiple domain
• hexists : Determine if a hash field exists
• hget : Gets the value of the hash field
• Hgetall : Get all domain values
• Hincrby : Self-growing value of a hash int field
• Hkeys : Get hash all fields
• Hlen : Get the number of domains
• hmget : Bulk Get the value of a domain
• hmset : Bulk set values for a field
• hset : Setting the value of a field
• hvals: Get values for all domains

d) list read and write function

• linsert: inserting elements
• llen: List length
• lpop: Remove and get the first color
• lpush: Inserting an element
• lrem: removing elements
• lSet: Setting element values

E) Set

• sadd: Add one or more members
• Sismember: Whether it contains
• smembers: Get member
• Smove: Moving Members
• SPop: removing members
• srandmember: Get random Members
• Srem: Delete

f) Sorted set

• zadd: Add one or more
• Zcard: Number of Members
• Zincrby: incrementing member score
• Zrange: Returns a member within an index range
• Zrangebyscore : Returns members within the score range
• Zscore: Get member Score
• zrem: Remove one or more members

Example:

<?php $redis = new Redis ();//Instantiate Redis class file $redis->connect (' 127.0.0.1 ', 6379); Connect to Redis server $redis->set (' name ', ' Zhangsan ');//Set value echo $redis->get (' name ');//Get value
