Detailed explanation of PHP using Redis instances

In this article, we mainly share with you detailed examples of using Redis in PHP, hoping to help everyone.

Before starting to use Redis in PHP, we need to ensure that the redis service and PHP redis driver have been installed, and that PHP can be used normally on your machine. Next, let us install the PHP redis driver: The download address is: https://github.com/phpredis/phpredis/releases.

PHP installation redis extension

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

$ wget https://github.com/phpredis/phpredis/archive/3.1.4.tar.gz$ cd phpredis-3.1.4                      # 进入 phpredis 目录$ /usr/local/php/bin/phpize              # php安装后的路径$ ./configure --with-php-config=/usr/local/php/bin/php-config
$ make && make install

Modify the php.ini file

vi /usr/local/php/lib/php.ini

Add the following content;

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. Check the phpinfo information and you can see the redis extension.

Connect to the redis service

<?php
    //连接本地的 Redis 服务
   $redis = new Redis();
   $redis->connect('127.0.0.1', 6379);
   echo "Connection to server sucessfully";
         //查看服务是否运行
   echo "Server is running: " . $redis->ping();
?>

Execute the script, the output result is:

Connection to server sucessfullyServer is running: PONG

Redis PHP String( String) instance

   //连接本地的 Redis 服务
   $redis = new Redis();
   $redis->connect('127.0.0.1', 6379);
   echo "Connection to server sucessfully";
   //设置 redis 字符串数据
   $redis->set("tutorial-name", "Redis tutorial");
   // 获取存储的数据并输出
   echo "Stored string in redis:: " . $redis->get("tutorial-name");
?>

Execute the script, the output result is:

Connection to server sucessfullyStored string in redis:: Redis tutorial

Redis PHP List (list) instance

<?php
   //连接本地的 Redis 服务
   $redis = new Redis();
   $redis->connect('127.0.0.1', 6379);
   echo "Connection to server sucessfully";
   //存储数据到列表中
   $redis->lpush("tutorial-list", "Redis");
   $redis->lpush("tutorial-list", "Mongodb");
   $redis->lpush("tutorial-list", "Mysql");
   // 获取存储的数据并输出
   $arList = $redis->lrange("tutorial-list", 0 ,5);
   echo "Stored string in redis";
   print_r($arList);
?>
