Question

Hello开发人员，

我目前正在尝试用imap阅读所有电子邮件。我试图用imap_headerinfo获取标题信息，并使用imap_fetchbody获取标题信息。但是，我得到了所有的headerinfo，但我只得到一个空字符串作为fetchbody函数的返回。我希望有人可以帮助我

$this->inbox = imap_open($server, $user, $password);

    // Header und Body der Email auslesen
    $emails = imap_search($this->inbox,'ALL');
    foreach($emails as $k) {
        $this->email_contents[$k] = array(
            'header' => imap_headerinfo($this->inbox, $k),
            'body' => imap_fetchbody($this->inbox, $k, '1')
        );
    }
    imap_close($this->inbox);

fetch_structure

imap-fetchbody（）在处理附加的电子邮件时异常工作，并且它的行为不一致。

我打算重新写这篇文章，但说实话，作者atamido非常出色地说明了为什么会这样，所以我谦卑地引用他的主要评论:: http://php.net/manual/en/function.imap-fetchbody.php他还包括一个如何提取身体的例子

imap-fetchbody（）将解码附加的电子邮件消息其余的电子邮件部分，但处理时的工作方式附加的电子邮件与主电子邮件消息不一致。使用只有文本正文但没有任何mime附件的电子邮件，imap-fetchbody（）将返回以下内容对于每个要求的部件号：
(empty) - Entire message
0 - Message header
1 - Body text
    With an email message that is a multi-part message in MIME format, and contains the message text in plain text and HTML, and has
一个file.ext附件，imap-fetchbody（）将返回类似的内容以下是每个要求的部件号：
(empty) - Entire message
0 - Message header
1 - MULTIPART/ALTERNATIVE
1.1 - TEXT/PLAIN
1.2 - TEXT/HTML
2 - file.ext
现在，如果您将上述电子邮件附加到包含纯文本和HTML的邮件文本的电子邮件中，则imap_fetchbody（）将使用此类型的零件号系统：
(empty) - Entire message
0 - Message header
1 - MULTIPART/ALTERNATIVE
1.1 - TEXT/PLAIN
1.2 - TEXT/HTML
2 - MESSAGE/RFC822 (entire attached message)
2.0 - Attached message header
2.1 - TEXT/PLAIN
2.2 - TEXT/HTML
2.3 - file.ext
请注意，file.ext现在与纯文本和   HTML，并且无法访问MULTIPART / ALTERNATIVE   附上的消息。

以下是以前帖子中某些代码的修改版本   这将构建一个包含可访问的易于访问的数组   如果没有多部分，则附加消息部分和消息正文   默剧。 $ structure变量是。的输出   imap_fetchstructure（）函数。返回的$ part_array有   字段＆＃39; part_number＆＃39;其中包含要直接送入的部件号   进入imap_fetchbody（）函数。

<?php
function create_part_array($structure, $prefix="") {
    //print_r($structure);
    if (sizeof($structure->parts) > 0) {    // There some sub parts
        foreach ($structure->parts as $count => $part) {
            add_part_to_array($part, $prefix.($count+1), $part_array);
        }
    }else{    // Email does not have a seperate mime attachment for text
        $part_array[] = array('part_number' => $prefix.'1', 'part_object' => $obj);
    }
   return $part_array;
}
// Sub function for create_part_array(). Only called by create_part_array() and itself. 
function add_part_to_array($obj, $partno, & $part_array) {
    $part_array[] = array('part_number' => $partno, 'part_object' => $obj);
    if ($obj->type == 2) { // Check to see if the part is an attached email message, as in the RFC-822 type
        //print_r($obj);
        if (sizeof($obj->parts) > 0) {    // Check to see if the email has parts
            foreach ($obj->parts as $count => $part) {
                // Iterate here again to compensate for the broken way that imap_fetchbody() handles attachments
                if (sizeof($part->parts) > 0) {
                    foreach ($part->parts as $count2 => $part2) {
                        add_part_to_array($part2, $partno.".".($count2+1), $part_array);
                    }
                }else{    // Attached email does not have a seperate mime attachment for text
                    $part_array[] = array('part_number' => $partno.'.'.($count+1), 'part_object' => $obj);
                }
            }
        }else{    // Not sure if this is possible
            $part_array[] = array('part_number' => $prefix.'.1', 'part_object' => $obj);
        }
    }else{    // If there are more sub-parts, expand them out.
        if (sizeof($obj->parts) > 0) {
            foreach ($obj->parts as $count => $p) {
                add_part_to_array($p, $partno.".".($count+1), $part_array);
            }
        }
    }
}
?>

imap_body（）返回空字符串
