Mailparse（邮件解析）

此 PECL 扩展未与 PHP 捆绑。 安装此 PECL 扩展相关的信息可在手册中标题为 PECL 扩展的安装章节中找到。更多信息如新的发行版本、下载、源文件、 维护人员信息及变更日志等，都在此处： https://pecl.php.net/package/mailparse.

为了使用这些函数，必须使用--enable-mailparse编辑选项。Windows用户使用php_mailparse.dllPECL 扩展的 DLL 当前不可用。参见 在 Windows 上构建章节。

必须在mailparse之前加载mbstring扩展

[Authors note:
The tarball for 4.2.x can be found here:

and contains a script called try.php that demonstrates the usage of these functions.

I've pasted the contents of the file below:
<?php
/*
 * This is a simple email viewer.
 * make sure that $filename points to a file containing an email message and
 * load this page in your browser.
 * You will be able to choose a part to view.
 * */
$filename = "uumsg";
/* parse the message and return a mime message resource */
$mime = mailparse_msg_parse_file($filename);
/* return an array of message parts - this contsists of the names of the parts
 * only */
$struct = mailparse_msg_get_structure($mime);
echo "<table>\n";
/* print a choice of sections */
foreach($struct as $st) {
    echo "<tr>\n";
    echo "<td><a href=\"$PHP_SELF?showpart=$st\">$st</a></td>\n";
    /* get a handle on the message resource for a subsection */
    $section = mailparse_msg_get_part($mime, $st);
    /* get content-type, encoding and header information for that section */
    $info = mailparse_msg_get_part_data($section);
    echo "\n";
    echo "<td>" . $info["content-type"] . "</td>\n";
    echo "<td>" . $info["content-disposition"] . "</td>\n";
    echo "<td>" . $info["disposition-filename"] . "</td>\n";
    echo "<td>" . $info["charset"] . "</td>\n";
    echo "</tr>";
}
echo "</table>";
/* if we were called to display a part, do so now */
if ($showpart) {
    /* get a handle on the message resource for the desired part */
    $sec = mailparse_msg_get_part($mime, $showpart);
    echo "<table border=1><tr><th>Section $showpart</th></tr><tr><td>";
    ob_start();
    /* extract the part from the message file and dump it to the output buff
er
     * */
    mailparse_msg_extract_part_file($sec, $filename);
    $contents = ob_get_contents();
    ob_end_clean();
    /* quote the message for safe display in a browser */
    echo nl2br(htmlentities($contents)) . "</td></tr></table>";;
}
