Before we start using Redis in PHP, we need to make sure that the redis service and PHP redis driver are installed and that PHP is working properly on your machine. L et's install the PHP redis driver: download address: https://github.com/nicolasff/phpredis.
/usr/local/php/bin/phpize #php安装后的路径 ./configure --with-php-config=/usr/local/php/bin/php-config make && make install
vi /usr/local/php/lib/php.ini
Add the following:
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20090626" extension=redis.so
Restart php-fpm or apache when the installation is complete. If you look at the phpinfo information, you can see the redis extension.
<?php //连接本地的 Redis 服务 $redis = new Redis(); $redis->connect('127.0.0.1', 6379); echo "Connection to server sucessfully"; //查看服务是否运行 echo "Server is running: "+ $redis->ping(); ?>
Execute the script and the output is:
Connection to server sucessfully Server is running: PONG
<?php //连接本地的 Redis 服务 $redis = new Redis(); $redis->connect('127.0.0.1', 6379); echo "Connection to server sucessfully"; //设置 redis 字符串数据 $redis->set("tutorial-name", "Redis tutorial"); // 获取存储的数据并输出 echo "Stored string in redis:: " . $redis->get("tutorial-name");
?>
Execute the script and the output is:
Connection to server sucessfully Stored string in redis:: Redis tutorial
<?php //连接本地的 Redis 服务 $redis = new Redis(); $redis->connect('127.0.0.1', 6379); echo "Connection to server sucessfully"; //存储数据到列表中 $redis->lpush("tutorial-list", "Redis"); $redis->lpush("tutorial-list", "Mongodb"); $redis->lpush("tutorial-list", "Mysql"); // 获取存储的数据并输出 $arList = $redis->lrange("tutorial-list", 0 ,5); echo "Stored string in redis:: " print_r($arList); ?>
Execute the script and the output is:
Connection to server sucessfully Stored string in redis:: Redis Mongodb Mysql
<?php //连接本地的 Redis 服务 $redis = new Redis(); $redis->connect('127.0.0.1', 6379); echo "Connection to server sucessfully"; // 获取数据并输出 $arList = $redis->keys("*"); echo "Stored keys in redis:: " print_r($arList); ?>
Execute the script and the output is:
Connection to server sucessfully Stored string in redis:: tutorial-name tutorial-list
