要在PHP程序中使用Redis,首先需要確保 Redis 的PHP驅動程序和 PHP 安裝設置在機器上。可以查看 PHP教程 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。下載完成以後,將文件解壓縮到 phpredis 目錄。在 Ubuntu 上安裝這個擴展,可使用如下圖所示的命令來安裝。
cd phpredis sudo phpize sudo ./configure sudo make sudo make install
現在,復制和粘貼“modules”文件夾的內容復制到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。
<?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,會產生下面的結果:
Connection to server sucessfully Server is running: PONG
<?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"); ?>
當執行程序時,會產生下面的結果:
Connection to server sucessfully Stored string in redis:: Redis tutorial
<?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,會產生下面的結果:
Connection to server sucessfully Stored string in redis:: Redis Mongodb Mysql
<?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,會產生下面的結果:
Connection to server sucessfully Stored string in redis:: tutorial-name tutorial-list
