从php中提取包含正文部分的所有邮件头文件

问题描述：

我想在php中使用正则表达式从下面的链式邮件中提取正文部分。连锁邮件以txt格式保存。在提取时，如果在body标签中存在html标签，则应该保持不变。从php中提取包含正文部分的所有邮件头文件

是我用来获取上述O/P的正则表达式

preg_match_all('/(?<=Subject:)(.*?[\n][\s]*?)(?=From:)/is',$content,$rest);

，但它并没有给出最后的一个，因为它没有 '从'获取中间数据。希望它清楚。请让我知道是否也有其他方法，为此。

preg_match_all('/(?m:^From:\x20(?<From>[^\n]*)\n^Sent:\x20(?<Sent>[^\n]*)\n^To:\x20(?<To>[^\n]*)\n(?:^Cc:\x20(?<Cc>[^\n]*)\n)?^Subject:\x20(?<Subject>[^\n]*)\n)(?<Body>.*?(?=(?:\nFrom:)|$))/s',$content,$matches); 
echo "<pre>".print_r($matches,true);

它提供了近正确的O/p.Should我提供http://www.mangalsutrabandhan.com

我不知道如果正则表达式是最好的选择。你最好根据/从/主题数据的“簇”来分割文档。从那里，任何内容都应该被视为内容。 –

你会编辑你的问题，以澄清所需的输出？ – paulmelnikow

答

你会需要一些更聪明的解析，以使这个意义上的文本文件 - 无论生成此文件改变电子邮件的结构：

Subject: Re: bride search 
PFA

应该有什么似乎是一个电子邮件标题的一部分，它的身体之间至少有一个空行。

然后你有问题top-posting（你不能依赖不知道时区的标题中的时间戳），不完整的标题和no quoting。

所以，即使你建立了一个启发式来解析这个，它有太多的场景，它不会应付。
