在PHP程序中使用Redis，需要确保我们有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。下载了它以后，将文件解压缩到phpredis目录。然后依次执行如下操作：
cd phpredis sudo phpize sudo ./configure sudo make sudo make install
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。
extension = redis.so
现在Redis的php驱动程序安装完毕。
使用php连接到Redis服务器
<?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();
当执行程序时，会产生下面的结果：
Connection to server sucessfully Server is running: PONG
Redis的PHP字符串实例
<?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:: " + jedis.get("tutorial-name");
当执行程序时，会产生下面的结果：
Connection to server sucessfully Stored string in redis:: Redis tutorial
Redis的PHP列表示例
<?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);
当执行程序时，会产生下面的结果：
Connection to server sucessfully Stored string in redis:: Redis Mongodb Mysql
Redis的PHP键例
<?php
//Connecting to Redis server on localhost
$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);
当执行程序时，会产生下面的结果：
Connection to server sucessfully Stored string in redis:: tutorial-name tutorial-list
