Mailparse Functions

简介

Mailparse is an extension for parsing and working with email messages. It can deal with » RFC 822 and » RFC 2045 (MIME) compliant messages.

Mailparse is stream based, which means that it does not keep in-memory copies of the files it processes - so it is very resource efficient when dealing with large messages.

Note: Mailparse requires the mbstring extension, and mbstring must be loaded before mailparse.

本扩展已被移动到 » PECL 库中且自以下版本起不再被绑定到 PHP 中:4.2.0.

安装

» PECL 扩展未绑定于 PHP 中。 安装此 PECL 扩展库的信息可在手册中标题为 PECL 扩展库安装的一章中找到。 更多信息如新版本,下载,源文件,维护者信息以及更新日志等可以在这里找到: » http://pecl.php.net/package/mailparse.

In order to use these functions you must compile PHP with mailparse support by using the --enable-mailparse configure option.

Windows users will enable php_mailparse.dll inside of php.ini in order to use these functions. 可以从 » PHP 下载页面或者 » http://snaps.php.net/ 下载此 PECL 扩展的 DLL 文件。

运行时配置

这些函数的行为受 php.ini 的影响。

Mailparse configuration options
Name Default Changeable Changelog
mailparse.def_charset "us-ascii" PHP_INI_ALL Available since PHP 4.1.0. Removed in PHP 4.2.0.
有关 PHP_INI_* 常量进一步的细节与定义参见php.ini 配置选项

预定义常量

以下常量由本扩展模块定义,因此只有在本扩展模块被编译到 PHP 中,或者在运行时被动态加载后才有效。

MAILPARSE_EXTRACT_OUTPUT (integer)
MAILPARSE_EXTRACT_STREAM (integer)
MAILPARSE_EXTRACT_RETURN (integer)

Also dont forget to LOAD mbstring before you load mailparse

example in the php.ini place in this order:

extension=php_mbstring.dll
extension=php_mailparse.dll

Or you will get an error.

Example how to handle mail content from a variable:

<?php

$buffer
= [...] // Mail Content from pipe or whatever

$mail = mailparse_msg_create();
mailparse_msg_parse($mail,$buffer);
$struct = mailparse_msg_get_structure($mail);

foreach(
$struct as $st) {
   
$section = mailparse_msg_get_part($mail, $st);
   
$info = mailparse_msg_get_part_data($section);
   
   
print_r($info);
}

?>

[Authors note:
The tarball for 4.2.x can be found here:
http://thebrainroom.com/opensource/php/mailparse.php
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>";;
}
?>
