PHP連接Redis

在php程序中使用Redis之前，需要確保在機器上安裝了Redis的PHP驅動程序和PHP環境。可以先在將PHP電腦上並配置好環境。

安裝

現在，讓我們看看如何設置Redis PHP驅動程序。
從github庫下載phpredis=> http://github.com/nicolasff/phpredis。 當下載它之後，提取文件到phpredis目錄。在Ubuntu上，安裝以下擴展。

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

現在，將「modules」文件夾的內容複製並粘貼到PHP擴展目錄中，並在php.ini中添加以下行。

extension = redis.so

現在，Redis PHP安裝完成！

使用連接到Redis服務器

<?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(); 
?>

當程序執行時，將產生以下結果。

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"); 
?>

執行上面代碼，將生成以下結果 -

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); 
?>

執行上面代碼，將生成以下結果 -

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

Redis php鍵示例

<?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); 
?>

執行上面代碼，將生成以下結果 -

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