Redis Learning (ii)

By learning from Redis (i), it is now possible to apply the Redis, which is mainly about PHP redis!

The test is as follows:

First, install the Redis extension for PHP: Php_redis.dll (version: Php5.2_redis)

my: Http://pan.baidu.com/s/1gdzRTHh

Put the extracted files (php_redis.dll) in the PHP package directory!

such as: D:\AppServ\php5\ext

Then...

Opens the php.ini file, essentially in C:\Windows\php.ini

Extension=php_redis.dll (PS: The front does not add ";", will be commented out)

Last reboot under apache!

So far, all of our configurations have been completed!

So happy!

PHP: Test Code

<?php$redis = new Redis (), $redis->connect ("127.0.0.1", 6379), $redis->set ("name", "Mao Ye Ye"), Echo $redis- >get ("name");

Redisis an open-source, high-performance key-Value Store (Key-value Store). It is often referred to as a data structure server (Data Structure Server). RedisThe key value can include a string (Strings) type, and it also includes a hash (Hashes), List (lists), collection (sets) and an ordered set (Sorted Sets) and other data types. For these data types, you can perform atomic operations. For example, attaching an operation to a string (Appendincrement the value in the hash, add the element to the list, calculate the intersection of the set, the set and the difference set, and so on.

in order to achieve excellent performance, Redis uses in-memory ( in-memory ) Data Set ( DataSet ) in a way. At the same time,Redis supports data persistence, you can dump the dataset to disk at intervals (snapshot), or append each action command at the end of the log ( Append only file,aof).

redis also supports master-slave replication ( master-slave replication  non-blocking. Synchronization redis There are some other features, These include simple things support, publish subscriptions (  pub/sub pipeline VM

Redis a rich client that supports most of the programming languages that are popular at this stage.
