php 创建临时id

ID3 Tags Reader with PHP Today we will work with PHP again. Today’s tutorial will tell you about how you can use PHP to obtain ID3 meta info from music files (mp3). The easiest way to save id3 info – winamp software (try to find it in old archives). So you will able to test our result script with your music files. We will extract next fields: Title, Album, Author, Discription, Genre, Publisher, OriginalArtist, URL etc.

使用PHP的ID3标签阅读器今天，我们将再次使用PHP。今天的教程将告诉您如何使用PHP从音乐文件(mp3)中获取ID3元信息。保存id3信息的最简单方法-winamp软件(尝试在旧的归档文件中找到它)。因此，您将能够使用您的音乐文件测试我们的结果脚本。我们将提取下一个字段：标题，专辑，作者，标题，类型，出版商，原始艺术家，URL等。

Now – download the example files and lets start coding !

现在，下载示例文件并开始编码！

步骤1. HTML (Step 1. HTML)

As usual, we start with the HTML. This is source of demo page layout:

和往常一样，我们从HTML开始。这是演示页面布局的来源：

main_page.html (main_page.html)


<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head><title>ID3 Tags Reader with PHP | Script-tutorials</title><link rel="stylesheet" href="css/main.css" type="text/css" media="all" />
</head>
<body><div class="example" id="main"><table style="width:100%"><thead><td><b>Title</b></td><td><b>Album</b></td><td><b>Author</b></td><td><b>AlbumAuthor</b></td><td><b>Track</b></td><td><b>Year</b></td><td><b>Lenght</b></td><td><b>Lyric</b></td><td><b>Desc</b></td><td><b>Genre</b></td></thead>__list__</table><hr /><h3>Extra info</h3><table style="width:100%"><thead><td><b>Title</b></td><td><b>Encoded</b></td><td><b>Copyright</b></td><td><b>Publisher</b></td><td><b>OriginalArtist</b></td><td><b>URL</b></td><td><b>Comments</b></td><td><b>Composer</b></td></thead>__list2__</table></div>
</body>
</html>

<head><title>ID3 Tags Reader with PHP | Script-tutorials</title><link rel="stylesheet" href="css/main.css" type="text/css" media="all" />
</head>
<body><div class="example" id="main"><table style="width:100%"><thead><td><b>Title</b></td><td><b>Album</b></td><td><b>Author</b></td><td><b>AlbumAuthor</b></td><td><b>Track</b></td><td><b>Year</b></td><td><b>Lenght</b></td><td><b>Lyric</b></td><td><b>Desc</b></td><td><b>Genre</b></td></thead>__list__</table><hr /><h3>Extra info</h3><table style="width:100%"><thead><td><b>Title</b></td><td><b>Encoded</b></td><td><b>Copyright</b></td><td><b>Publisher</b></td><td><b>OriginalArtist</b></td><td><b>URL</b></td><td><b>Comments</b></td><td><b>Composer</b></td></thead>__list2__</table></div>
</body>
</html>

I prepared 2 tables to display ID3 infos of each enumerated file

我准备了2个表格来显示每个枚举文件的ID3信息

步骤2. CSS (Step 2. CSS)

Here are used CSS styles:

以下是使用CSS样式：

css / main.css (css/main.css)


body{background-color:#ddd;margin:0;padding:0}
.example{position:relative;background-color:#fff;width:980px;height:700px;border:1px #000 solid;margin:20px auto;padding:20px;-moz-border-radius:3px;-webkit-border-radius:3px}


body{background-color:#ddd;margin:0;padding:0}
.example{position:relative;background-color:#fff;width:980px;height:700px;border:1px #000 solid;margin:20px auto;padding:20px;-moz-border-radius:3px;-webkit-border-radius:3px}

步骤3. PHP (Step 3. PHP)

Our most important part of project – PHP.

我们项目中最重要的部分– PHP。

After put your mp3 files near these code files thats all. Yes, there are a lot of code, but everything is close. Commonly – you can check code in beginning (before defining of class), and class itself. First half is very easy – passing through files of folder, and generating output. So about class itself (ID3TagsReader) – this is more difficult. We will read hex code of each MP3 file and looking for inner information (ID3). I will try to pick all ID3 tags which can be available in Winamp (mp3 player). But I can say that the total of all possible tags is much more.

将您的mp3文件放在这些代码文件附近之后。是的，有很多代码，但是一切都很接近。通常-您可以在开始定义类之前检查代码，以及类本身。上半部分非常简单–遍历文件夹文件并生成输出。因此，关于类本身(ID3TagsReader)–这更困难。我们将阅读每个MP3文件的十六进制代码，并查找内部信息(ID3)。我将尝试选择所有可以在Winamp(mp3播放器)中使用的ID3标签。但是我可以说所有可能的标签的总数更多。
