安裝

在PHP程序中使用Redis，需要確保我們有Redis的PHP驅動程序和PHP安裝設置在機器上。可以查看PHP教學教你如何在機器上安裝PHP。現在，讓我們來看看一下如何設置Redis的PHP驅動程序。

需要從github上資料庫https://github.com/nicolasff/phpredis下載phpredis。下載了它以後，將文件解壓縮到phpredis目錄。在Ubuntu上安裝這個擴展，如下圖所示。

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

現在，複製和粘貼“modules”文件夾的內容複製到PHP擴展目錄中，並在php.ini中添加以下幾行。

extension = redis.so

現在Redis和PHP安裝完成。

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();
?>

當執行程序時，會產生下麵的結果：

Connection to server sucessfully
Server is running: PONG

Redis的PHP字符串實例

<?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");
?>

當執行程序時，會產生下麵的結果：

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);
?>

當執行程序時，會產生下麵的結果：

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

Redis的PHP鍵例

<?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);
?>

當執行程序時，會產生下麵的結果：

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