有没有免费的PHP库可以解析.mobi文件以获得：
- 作者
- 标题
- Publisher
- 封面

对于那些认为这是《PHP库是否存在以处理PRC/MOBI文件》的精确复制的人来说，你显然懒得阅读这些问题。
该询问者想知道如何使用PHP库生成.mobi文件。我想知道如何分解或解析已经创建的.mobi文件以获得某些信息。因此，这个问题的解决方案phpMobi将不起作用，因为它是一个从HTML生成.mobi文件的脚本，而不是解析.mobi。
这是一个非常非常蹩脚的例子，但如果你绝望了，你可以尝试这样的方法：
$data = file_get_contents("A Young Girl's Diary - Freud, Sigmund.mobi");
$chunk = mb_substr($data, mb_strpos($data, 'EXTH'), 512);
$chunks = explode("'x00", $chunk);
array_shift($chunks);
$chunks = array_filter($chunks, function($str){return preg_match('#([A-Z])#', $str) && mb_strlen($str) > 2;});
$chunks = array_combine(array('author', 'publisher', 'title'), $chunks);
print_r($chunks);
输出：
Array
(
[author] => Freud, Sigmund
[publisher] => Webarto
[title] => A Young Girl's Diary
)
使用的文件：http://freekindlebooks.org/Freud/752-h.mobi（使用Calibre编辑发布者元数据）
文件解析甚至不是一件容易或有趣的事情。看看这个：http://code.google.com/p/xee/source/browse/XeePhotoshopLoader.m?r=a70d7396356997114b548f4ab2cbd49badd7d285#107
你应该做的是逐字节读取，但由于没有详细的文档，恐怕这不是一项容易的工作。
第页。S.我还没试着去拿封面照片。
如果有人仍然感兴趣，这里有一个mobi元数据读取示例：

public $Type = 0;
public $Encoding = 0;
public $Id = 0;

}

也有同样的问题，没有找到任何PHP解析器，不得不自己编写（不幸的是，我不能透露我的代码）。这里有一个关于.mobi结构的好资源http://wiki.mobileread.com/wiki/MOBI
