PHP uses Redis

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 is working properly on your machine. L et's install the PHP redis driver: download address: https://github.com/nicolasff/phpredis.

PHP installs the redis extension

/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:

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20090626"

extension=redis.so

Restart php-fpm or apache when the installation is complete. If you look at the phpinfo information, 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();
