PHP with Redis

Installation

Before starting to use Redis in PHP, We need to make sure that the redis service and PHP redis driver are installed, and that PHP can be used normally on your machine. Next, let's install the PHP redis driver: download address is:https://github.com/phpredis/phpredis/releases.

PHP install 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　　　　　　　　　　　　　　　　　　　　　　# 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

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 after installation-fpm or apache. Check phpinfo information to see the redis extension.

Connect to the redis service

<?php
　　　　//Connect to the local Redis server
　　　$redis = new Redis();
　　　$redis->connect('127.0.0.1',　6379);
　　　echo "Connection to server successfully";
　　　　　　　　　//Check if the service is running
　　　echo "Server is running: " . $redis->ping();
?>

Execute the script, the output is:
