PHP 使用redis

<?php

/*从平台获取数据库名*/

$dbname = "";

/*从环境变量里取host,port,user,pwd*/

$host = '';

$port = '';

$user = '';

$pwd = '';

try {

    /*建立连接后，在进行集合操作前，需要先进行auth验证*/

    $redis = new Redis();

    $ret = $redis->connect($host, $port);

    if ($ret === false) {

	die($redis->getLastError());

    }

    $ret = $redis->auth($user . "-" . $pwd . "-" . $dbname);

    if ($ret === false) {

	die($redis->getLastError());

    }

    /*接下来就可以对该库进行操作了，具体操作方法请参考phpredis官方文档*/

    $redis->flushdb();

    $ret = $redis->set("key", "value");

    if ($ret === false) {

	die($redis->getLastError());

    } else {

	echo "OK".$redis->get("key");

    }

} catch (RedisException $e) {

    die("Uncaught exception " . $e->getMessage());

}

?>
