This article mainly introduces the meaning of redis in php. It has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

In php, redis, whose full name is Remote Dictionary Server (remote data Service), is an in-memory cache database whose data model is "key-value" and supports rich data structures, such as string, list, hash, etc., and can be persisted to ensure data security.

Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

Redis is the abbreviation of Remote Dictionary Server (remote data Service), an in-memory cache database developed by Italian Antirez (Salvatore Sanfilippo). It is written in C language, its data model is key-value, and supports rich data structures (types), such as string, list, hash, set, sorted sort. It can be persisted to ensure the security of data.

Redis is an open source API that is written in ANSI C language, supports the network, can be memory-based and persistent, and provides API in multiple languages.

One of the main differences between Redis and other key-value databases is the ability of Redis to store and manipulate advanced data types. These data types are basic data structures (lists, mappings, collections, and sort sets) that most developers are familiar with. Redis's excellent performance, simplicity and atomic operation of data structures help to solve the problems that are difficult to implement or perform poorly when using traditional relational database implementations.

PHP uses Redis

Installation

Before we start using Redis in PHP, we need to make sure that the redis service and PHP redis driver are installed and that PHP can be used properly on your machine. Next, let's install the PHP redis driver: download it at https://github.com/phpredis/phpredis/releases.

PHP installs the redis extension

The following operations need to be done in the downloaded phpredis directory:

$wget https://github.com/phpredis/phpredis/archive/2.2.4.tar.gz$ cd phpredis-2.2.7 # enter the phpredis directory $/ usr/local/php/bin/phpize # php installation path $. / configure-- with-php-config=/usr/local/php/bin/php-config$ make & & make install

If you are in the PHP7 version, you need to download the specified branch:

Git clone-b php7 https://github.com/phpredis/phpredis.git

Modify the php.ini file

Vi / usr/local/php/lib/php.ini

Add the following:

Extension_dir = "/ usr/local/php/lib/php/extensions/no-debug-zts-20090626" extension=redis.so

Restart php-fpm or apache after the installation is complete. Look at the phpinfo information and you can see the redis extension.
