要在PHP程序中使用Redis，首先需要确保 Redis 的PHP驱动程序和 PHP 安装设置在机器上。可以查看 PHP教程 教你如何在机器上安装PHP。现在，让我们来看看一下如何设置 Redis 的PHP驱动程序。
需要从 github 上资料库： https://github.com/nicolasff/phpredis 下载 phpredis。下载完成以后，将文件解压缩到 phpredis 目录。在 Ubuntu 上安装这个扩展，可使用如下图所示的命令来安装。
<span class="pln"> cd phpredis sudo phpize sudo ./configure sudo make sudo make install </span>
现在，复制和粘贴“modules”文件夹的内容复制到PHP扩展目录中，并在 php.ini 中添加以下几行。
<span class="pln"> extension = redis.so </span>
现在 Redis 和 PHP 安装完成。
<span class="pln">
<?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();
?>
</span>当执行程序时，会产生下面的结果：
<span class="pln"> Connection to server sucessfully Server is running: PONG </span>
<span class="pln">
<?php

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

//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");
?>
</span>当执行程序时，会产生下面的结果：
<span class="pln"> Connection to server sucessfully Stored string in redis:: Redis tutorial </span>
<span class="pln">
<?php

$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);
?>
