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。下載了它以后，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，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。
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，會產生下面的結果：
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，會產生下面的結果：
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，會產生下面的結果：
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，會產生下面的結果：
Connection to server sucessfully Stored string in redis:: tutorial-name tutorial-list
