Redis series-php how to use redis extension through redis

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 # <SPAN style = "TEXT-INDENT: 20px "> suppose php Directory: </SPAN> <SPAN style =" TEXT-INDENT: 20px ">/usr/local/php </SPAN> [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 # assume the 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 smooth, the following is a reference. Description: [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 extension file directory, there will be a redis. so file. B) Load redis. so in php. in the ini file, add the configuration: [plain] [redis] extension = redis. so [redis] extension = redis. so restart the web server, echo phpinfo (), will see roughly as follows: 2. How to access the redis server through extended access php using the redis server to access data? It is nothing more than the phpredis extension module, through the following steps: 1. instantiate the redis class [new redis ()] 2. Call the redis class method to connect to the redis server [connect, pconnect: 3. Set the connection option setOption. 4. Store/retrieve data. 5. close the connection. If the default option is used, skip step 3. See the following code example: [php] <? Php $ redis = new Redis (); # instantiate redis class $ redis-> connect ('2017. 127. 0.0.1 '); # connect to the server $ redis-> set ('key', 'Hello'); # Call the method and set the string type value $ redis-> append ('key ', 'World'); # modify the string type value echo $ redis-> get ('key'); # obtain the redis key value, echo $ redis-> type ('key'); # obtain the data type of the key echo $ redis-> echo ('will close... '); # output string $ redis-> close (); # close the connection <? Php $ redis = new Redis (); # instantiate redis class $ redis-> connect ('2017. 127. 0.0.1 '); # connect to the server $ redis-> set ('key', 'Hello'); # Call the method and set the string type value $ redis-> append ('key ', 'World'); # modify the string type value echo $ redis-> get ('key'); # obtain the redis key value, echo $ redis-> type ('key'); # obtain the data type of the key echo $ redis-> echo ('will close... '); # output string $ redis-> close (); # close the connection through the above Code, we basically complete a simple redis access operation. Some attributes and methods of Redis are listed below. a) connect to redis server: connect to serverpconnect: persistent connection auth: Permission verification select: select DBclose: close connection setOption: set the client Option getOption: Get the client Option ping: ping redis server echo: Output string Note: If you operate redis frequently, non-stop connect and close will consume a lot of performance. At this time, we recommend that you use pconnect to establish a persistent connection B) string read/write function append: append value after the value decr: decrease the value of a key incr: Increase the value of a key get: get a value set: set a value getSet: set a value, and return the old value mGet: Batch get value mSet: Batch set value strlen: Get value length note: if you can use batch operations, try to use batch operations to reduce frequent connection to redis database performance c) hash read/write function hDel: delete multiple domains hExists: Determine whether a hash domain has hGet: get the value of the hash field hGetAll: Get the value of all domains hIncrBy: Increase the value of a hash int field hKeys: Get the hLen of all hash domains: Get the number of domains hmet: obtain the value of the domain in batches hMSet: batch 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 obtain the first color lPush: insert an element lRem: Remove element lSet: set element value e) set sAdd: add one or more Members sIsMember: whether it contains sMembers: get member sMove: Move member sPop: Remove member sRandMember: Get random member sRem: delete f) sorted set zAdd: add one or more zcards: Number of Members zIncrBy: incrementing member scorezRange: returns zRangeByScore, a member in the index range. Returns zScore, a member in the score range. obtains scorezRem. removes one or more members.
