PHPChina 的论坛看到有人问,如何使用 PHP 得到一个媒体的文件的播放时间,然后就自己尝试用 COM 写了一段代码,开始以为蛮复杂的,不过还好思路对了,只是在浩瀚的 MSDN 上查找 WMP SDK 的资料折腾的够呛,最后写出的代码却只有寥寥几行,代码如下:

<?php
 
// mp3, wav or any other file formats that media player supports.
$file = "C:/I Wanna Go To A Place.mp3";
if (!file_exists($file)) {
    exit('Media file does not exist.');
}
 
// Create an instance of Windows Media Player
$player = new COM("WMPlayer.OCX");
$media  = $player->newMedia($file);
 
// Get the duration of a media file (seconds)
print $media->duration;

在 PHP Manual 的 XV. COM and .Net (Windows) 一章,还看到一位叫 Pedro 的同学提交的利用 WMP OCX 弹出光驱的 PHP 代码
有兴趣的朋友可以玩玩:

<?php
// Create an instance of Windows Media Player
$mp = new COM("WMPlayer.OCX");
 
// Ejects the first cd-rom on the drive list
$mp->cdromcollection->item(0)->eject();
