Redis 简明教程

Redis - PHP

在 PHP 程序中使用 Redis 之前，需要确保计算机上已设置好 Redis PHP 驱动和 PHP。可以查看 PHP 教程，以在计算机上安装 PHP。

Installation

现在，让我们检查如何设置 Redis PHP 驱动。

需要从 github 存储库 https://github.com/nicolasff/phpredis 下载 phpredis。下载后，将文件解压到 phpredis 目录。在 Ubuntu 上，安装以下扩展程序。

cd phpredis
sudo phpize
sudo ./configure
sudo make
sudo make install

现在，将“modules”文件夹的内容复制并粘贴到 PHP 扩展目录，并在 php.ini 中添加以下行。

extension = redis.so

现在，Redis PHP 安装已完成

Connect to Redis Server

<?php
   //Connecting to Redis server on localhost
   $redis = new Redis();
   $redis->connect('127.0.0.1', 6379);
   echo "Connection to server sucessfully";
   //check whether server is running or not
   echo "Server is running: ".$redis->ping();
?>

此程序执行时将会显示以下结果。

Connection to server sucessfully
Server is running: PONG

Redis PHP String Example

<?php
   //Connecting to Redis server on localhost
   $redis = new Redis();
   $redis->connect('127.0.0.1', 6379);
   echo "Connection to server sucessfully";
   //set the data in redis string
   $redis->set("tutorial-name", "Redis tutorial");
   // Get the stored data and print it
   echo "Stored string in redis:: " .$redis→get("tutorial-name");
?>

执行上述程序后，它将产生以下结果。

Connection to server sucessfully
Stored string in redis:: Redis tutorial

Redis php List Example

<?php
   //Connecting to Redis server on localhost
   $redis = new Redis();
   $redis->connect('127.0.0.1', 6379);
   echo "Connection to server sucessfully";
   //store data in redis list
   $redis->lpush("tutorial-list", "Redis");
   $redis->lpush("tutorial-list", "Mongodb");
   $redis->lpush("tutorial-list", "Mysql");

   // Get the stored data and print it
   $arList = $redis->lrange("tutorial-list", 0 ,5);
   echo "Stored string in redis:: ";
   print_r($arList);
?>

执行上述程序后，它将产生以下结果。

Connection to server sucessfully
Stored string in redis::
Redis
Mongodb
Mysql

Redis PHP Keys Example

<?php

   $redis = new Redis();
   $redis->connect('127.0.0.1', 6379);
   echo "Connection to server sucessfully";
   // Get the stored keys and print it
   $arList = $redis->keys("*");
   echo "Stored keys in redis:: "
   print_r($arList);
?>

此程序执行时将会显示以下结果。

Connection to server sucessfully
