在php程序中使用Redis之前，需要确保在机器上安装了Redis的PHP驱动程序和PHP环境。可以先在将PHP电脑上并配置好环境。

安装

现在，让我们看看如何设置Redis PHP驱动程序。
从github库下载phpredis=> http://github.com/nicolasff/phpredis。 当下载它之后，提取文件到phpredis目录。在Ubuntu上，安装以下扩展。

cd phpredis 
sudo phpize 
sudo ./configure 
sudo make 
sudo make install

现在，将“modules”文件夹的内容复制并粘贴到PHP扩展目录中，并在php.ini中添加以下行。

extension = redis.so

现在，Redis PHP安装完成！

使用连接到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(); 
?>

当程序执行时，将产生以下结果。

Connection to server sucessfully 
Server is running: PONG

Redis PHP字符串示例

<?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 
   $redis->set("tutorial-name", "Redis tutorial"); 
   // Get the stored data and print it 
   echo "Stored string in redis:: " .$redis→get("tutorial-name"); 
?>

执行上面代码，将生成以下结果 –

Connection to server sucessfully 
Stored string in redis:: Redis tutorial

Redis 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); 
?>

执行上面代码，将生成以下结果 –

Connection to server sucessfully 
Stored string in redis:: 
Redis 
Mongodb 
Mysql

Redis php键示例

<?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); 
?>

执行上面代码，将生成以下结果 –

Connection to server sucessfully 
Stored string in redis:: 
tutorial-name 
tutorial-list
