安装
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。在Ubuntu上安装这个扩展，如下图所示。
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 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
