- 这可以使用preg_match($pattern,$data, $matches, PREG_OFFSET_CAPTURE)和substr吗？

Answer 1

您不能只使用preg_match来可靠地解析邮件。最好使用PHP Mime Mail Parser来执行此任务。使用Mime Mail Parser代码将非常简单：

require_once('MimeMailParser.class.php');

$path = 'path/to/mail.txt';

$Parser = new MimeMailParser();
$Parser->setPath($path);

$to       = $Parser->getHeader('to');
$from     = $Parser->getHeader('from');
$subject  = $Parser->getHeader('subject');
$textBody = $Parser->getMessageBody('text');
$htmlBody = $Parser->getMessageBody('html');
