php - 如何限制脚本在特定 ip 地址上运行的时间

Question

每当运行从表中选择歌曲的脚本时，我都会增加正在播放的歌曲数量的一些值，但我只想在假设 5 小时内增加一次。这意味着用户将播放一首歌曲，它只会在第一次播放时被计为一次播放，然后等待 5 小时，然后再允许另一次播放。

PHP

我只是不知道该怎么做。

$_SESSION['play_id'] = $_SERVER["REMOTE_ADDR"];
    $_SESSION['play_time'] = time();
    $then = $_SESSION['play_time'];
    $now  = time();
    $diff = $now->diff($then);
    if ($diff > 2 * 1000){
    $query = mysql_query("UPDATE music SET plays = plays + 1  WHERE sid = '$id'") or die (mysql_error());
    } else {
        echo 'not yet';
        }

谢谢。

$ip = 0
if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $ip = $_SERVER['HTTP_CLIENT_IP'];
} else {
    $ip = $_SERVER['REMOTE_ADDR'];
}

Security issue elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { $ip = $_SERVER['HTTP_X_FORWARDED_FOR']; }

$_SESSION['play_id'] = $ip;
        $_SESSION['play_time'] = time();
        $then = $_SESSION['play_time'];
        $now  = time();
        $diff = $now->diff($then);
        if ($diff > 2 * 1000){
        $query = mysql_query("UPDATE music SET plays = plays + 1  WHERE sid = '$id'") or die (mysql_error());
        } else {
            echo 'not yet';
            }
