安裝
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。下載完成以后,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,并在 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 notecho "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 itecho "Stored string in redis:: " . $redis.get("tutorial-name");
?>
當執行程序時,會產生下面的結果:
Connection to server sucessfully
Stored string in redis:: Redis tutorial
Redis的PHP列表示例
<?php//Connecting to Redis server on localhost$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
