我正在尝试将 Bohemian Rhapsody 的声音文件嵌入到我的网站中，并找到了以下代码片段：
echo "<embed src=\"SONGURL.mp3\" autostart=\"true\" loop=\"true\" hidden=\"true\"> </embed>\n" ."<noembed><bgsound src=\"SONGURL.mp3\" loop=\"infinite\"></noembed>";
我的问题是如何使它适用于我想要的歌曲？另外，我会修改其中的哪一部分？
Well it seems that the HTML snippet being produced by the PHP snippet in question relies on some sort of plug-in (my guess would be Flash, but I'm not familiar with Flash at all) so it would be much more complicated than a simple edit of the HTML string. If you're willing to break backwards compatibility with old browsers, you could use the HTML5 audio tag (see for example https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_HTML5_audio_and_video).
In your case, given some filename $song_url, you could accomplish what it seems you want via string-building as
$html_snippet = "<audio src=\"$song_url\" autoplay loop></audio>";
echo $html_snippet;
To support multiple different formats (for example .ogg files for Firefox users) you can simply write
$html_snippet = <<<EOD
<audio autoplay loop>
Upgrade to a newer browser!
<source src="$song_url_mp3" type="audio/mpeg">
<source src="$song_url_ogg" type="audio/ogg">
</audio>
EOD;
This HTML tag will ensure that your audio plays automatically and loops forever. To give users standard music controls, simply add a controls attribute.
