PHP的imap问题 [英] PHP imap problems

问题描述

我需要能够使用我的gmail从php脚本。但无论我尝试什么，消息体都会出现，像= 3D和随机符号等字符一样肮脏。有时它作为base64出现，或者什么也没有。如何获取电子邮件并在HTMLPurifier中清除html或纯文本，如果没有html可用。

I need to be able to use my gmail from a php script. But whatever I try, the message body comes out all crappy with characters like =3D and random equals signs. Sometimes it comes out as base64 or nothing at alls. How can I fetch an email and dispay it in HTMLPurifier clean html or plain text in a pre if no html is available.

$overview = imap_fetch_overview($inbox,$email_number,0);

$body_pre = imap_fetchbody($inbox, $email_number, 2.1); 

$message = imap_fetchbody($inbox, $email_number, 2.2); 

$message = base64_decode($message);

if (empty($message))
 {
  $message = $body_pre;
  $message = preg_replace('@(https?://([-\w\.]+)+(:\d+)?((/[\w/_\.%\-+~]*)?(\?\S+)?)?)@', '<a href="$1">$1</a>',$message);
$message = '<pre>'.htmlentities($message).'</pre>';  

}else{

 $cleanconfig = HTMLPurifier_Config::createDefault();
 $cleanconfig->set('Core.Encoding', 'UTF-8');
 $cleanconfig->set('HTML.Doctype', 'HTML 4.01 Transitional');
 $purifier = new HTMLPurifier($cleanconfig);

  $message = $purifier->purify($message);

 }

此代码，$消息只是空白。 >

this code, $message just comes blank.

推荐答案

你假设你的邮件总是在位置2.2？绝对没有保证...取决于发送什么消息你计划文本（只一个身体），html /文本（两个），附件（三加）回复另一个电子邮件（然后其他电子邮件将是一个身体与它是自己的子体）。

You're assuming your mail message is always at position 2.2? There's absolutely no guarantees... depends on what message is sent you plan text (just one body), html/text (two), with attachment (three plus) in reply to another email (then the other email will be a body with it's own sub bodies).

= 3D （引用的可打印）和base64数据是因为消息体编码。看看 imap_fetchstructure 它解释了他们在消息中有多少部分（您可以通过它查找文本来查找），并查看每个机构的 - >类型组件，以学习关于它的编码（type = 4是quotable可打印的，type = 3是base64）

The =3D (quoted printable) and base64 data are because of message body encodings. Have a look at imap_fetchstructure which explains how many parts their are on a message (you can search through it to find text), and review the ->type component of each body to learn about it's encoding (type=4 is quoted printable, type=3 is base64)
