1. Install PHP extension a) Install PHP extension Phpredis: [plain] [root@xsf002 tool]# git clone https://github.com/nicolasff/phpredis.git Phpredis [ root@xsf002 tool]# CD phpredis/[root@xsf002 phpredis]#/usr/local/php/bin/phpize # Suppose PHP directory: /usr/local/php [root@xsf002 phpredis]#./configure--with-php-config=/usr/local/php/bin/php-config [root@xsf002 phpredis]# make [ root@xsf002 phpredis]# make install [root@xsf002 tool]# git clone https://github.com/nicolasff/phpredis.git phpredis[ root@xsf002 tool]# cd phpredis/[root@xsf002 phpredis]#/usr/local/php/bin/phpize #假设 php Directory:/usr/local/php[root@xsf002 phpredis]#./configure--with-php-config=/usr/local/php/bin/php-config[root@xsf002 phpredis]# make[root@xsf002 phpredis]# make install if it goes well, you will get a prompt similar to the following: [Plain] Installing shared extensions:/usr/local/php/lib/php/extensions/ No-debug-non-zts-20060613/installing Shared extensions:/usr/local/php/lib/php/extensions/ no-debug-non-zts-20060613/php the extension file directory, there will be a redis.so file. b) Load redis.so in the php.ini file, add the configuration: [Plain] [Redis] extension=redis.so [redis]extension=redis.so Restart the Web server, Echo phpinfo (), You will see roughly the following: 2. Access to Redis server by extension How does PHP Access data using Redis server? It is only through the Phpredis expansion module, through the following steps: 1, Instantiate Redis class "New Redis ()" 2, call the Redis class method, connect Redis Server "Connect,pconnect" 3, set connection option "SetOption" 4, save/Fetch data 5, close connection "Close" If you use the default option, step 3 is not required. See the following code example: [PHP] Connect (' 127.0.0.1 '); #连接服务器 $redis->set (' key ', ' hello '); #调用方法, set the string type value $redis->append (' key ', ' world '); #修改string类型值 echo $redis->get (' key '); #获取redis the value of key, and the output shows echo $redis->type (' key '); #获取key data type echo $redis->echo (' would close ... '); # output String $redis->close (); #关闭连接 Connect (' 127.0.0.1 '); #连接服务器 $redis->set (' key ', ' hello '); #调用方法, set the string type value $redis->append (' Key ', ' world '); #修改string类型值echo $redis->get (' key '); #获取redis the value of key, and the output shows echo $redis->type (' key '); #获取key data type echo $redis->echo (' would close ... '); # output string $redis->close (); #关闭连接 through the above code, we basically complete a simple Redis access operation. Here are some of the properties and methods of the Redis Class A) connecting Redis Server:connect: Connection serverpconnect: Long connection Auth: Authorization Verification Select: Select dbclose: Close connection setOption: Set CLI ENT options getoption: Get client options ping:ping Redis server echo: Output string Note that if you operate redis frequently, connect and close will be very expensive, and this time, it is recommended to use the Pconnect Establish a long connection B) string read-write function append: Append value after value DECR: decrements the value of a key incr: increments the value of a key get: Gets a value set: Sets a value Getset: Sets the value and returns the old value mget: bulk Get value mset: Bulk Set Set value strlen: Get value Length Note: If you can use bulk operations as much as possible, reduce the frequent connection of Redis database performance C) hash read-write function Hdel: Delete a multiple domain hexists: Determine if a hash domain exists hget : Gets the value of the hash field Hgetall: Gets 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 the domain hmset: bulk Set the value of the field Hset : Set the value of the field Hvals: Get the value of all fields D) List read-write function Linsert: Insert element llen:list length Lpop: Remove and get first color Lpush: Insert an element lrem: remove element LSet: Set element value E) setSadd: Add one or more members Sismember: include Smembers: Get member Smove: Move member Spop: Remove member Srandmember: Get random member Srem: delete f) sorted set Zadd: Add one or more Zcard: number of members Zincrby: Increment member Scorezrange: Returns the member within the index range Zrangebyscore : Returns a member of the score range Zscore: Get member Scorezrem: remove one or more members
