示例很简单,注释里也都做了说明,这里就不多废话了。

代码如下:


/*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());
}
?>

以上就是本文所述的代码的全部内容了,希望大家能够喜欢。
