安装
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。
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 和 PHP 安装完成。
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 notecho "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 itecho "Stored string in redis:: " . $redis.get("tutorial-name");
?> 当执行程序时，会产生下面的结果：
Connection to server sucessfully
Stored string in redis:: Redis tutorial Redis的PHP列表示例
<?php//Connecting to Redis server on localhost$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
