Redis Installation succeededDownload

[Email protected] src]# wget

[[email protected] src]# ls

[[email protected] src]# unzip[[email protected] src]# CD Phpredis-master
[Email protected] src]#/usr/local/webserver/php/bin/phpize
[Email protected] src]#/configure--with-php-config=/usr/local/webserver/php/bin/php-config

[[email protected] src]# make && make install

[Email protected] src]# Vi/usr/local/webserver/php/etc/php.ini

Underneath the extension.

Restart Apache after saving, if it is a connected nginx, you will need to restart PHP-FPM.

Output phpinfo () under the Linux domain name;


Echo Phpinfo ();



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

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