Redis – PHP

在您的 PHP 程序中开始使用 Redis 之前，您需要确保在机器上安装了 Redis PHP 驱动程序和 PHP。您可以查看 PHP 教程以在您的机器上安装 PHP。

安装

现在，让我们检查如何设置 Redis PHP 驱动程序。

您需要从 github 存储库https://github.com/nicolasff/phpredis下载 phpredis 。下载后，将文件解压缩到 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，并在php.ini 中添加以下行。

extension = redis.so

现在，您的 Redis PHP 安装已完成

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(); 
?>

程序执行时，会产生如下结果。

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"); 
?>

执行上述程序时，将产生以下结果。

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); 
?>

执行上述程序时，将产生以下结果。

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

Redis PHP 密钥示例

<?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); 
?>

程序执行时，会产生如下结果。

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