我目前正在编写一个脚本来播放本地服务器上的随机mp3文件，并在屏幕顶部显示标题。但是，它似乎根本不起作用。
下面的一些代码已被删除，但这些是我用来随机选择一首歌然后显示标题的脚本，有什么建议吗？
<?php
// A Steam API Key is required so as to be able to contact steam and get a users profile image and name
// You can get a Steam API Key by visiting http://steamcommunity.com/dev/apikey
// Don't worry about the web address, it won't have any effect so just type in any web site
// Once you have your steam API Key simply paste the key below. (Make sure the quotation marks are still there or else it won't work)
$SteamAPIKey = "removed";
// Don't edit any of the PHP stuff here or else you may break the script
// If you website isn't displaying correctly then please make sure you have configured your loading url correctly
if (!isset($_GET["steamid"])) {
die("Woops, you don't seem to be using the correct loading URL format, please make sure it has the correct extension it should look like this: www.yourdomain.com/loading/index.php?steamid=%s");
}
$steamid64 = $_GET["steamid"];
$url = "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=" . $SteamAPIKey . "&steamids=" . $steamid64;
$json = file_get_contents($url);
$table2 = json_decode($json, true);
$table = $table2["response"]["players"];

您展示的代码没有做任何事情，使我们难以调试。您应该避免的一件事是使用关键字Number作为变量名称。这是一个简单的随机歌曲名称选择器：
var songlist = ["Tobu - Candyland", "Tobu - Colors", "Tobu - Dreams", "Tobu - Seven", "Tobu - Such Fun"];
alert(songlist[Math.floor(Math.random() * songlist.length)]);
