复制代码 代码如下:

<?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());
}
?>
