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
