EmailReplyParser is a port of the GitHub's EmailReplyParser library written in Ruby.

This is a small PHP library to parse plain text email content.

If you don't use a ClassLoader in your application, just require the provided autoloader:

<?php

require_once 'src/autoload.php';

You're done.

Instantiate an Email object and you're done:

<?php

$email = new \EmailReplyParser\Email();

$reply = $email->read($emailContent);
// same as:
$reply = $email->getFragments();

Alternatively, you can use the static way:

$reply = \EmailReplyParser\EmailReplyParser::read($emailContent);

$reply is an array of Fragment objects, i.e., $fragment = $reply[0];. To get the content of each fragment, call the getContent() method.

A Fragment can be a signature, a quoted text, or an hidden text. Here is the API:

<?php
$fragment = $reply[0];

// Get the content
$fragment->getContent();
// Whether the fragment is a signature or not
$fragment->isSignature();

// Whether the fragment is quoted or not
$fragment->isQuoted();

// Whether the fragment is hidden or not
$fragment->isHidden();

// Whether the fragment is empty or not
$fragment->isEmpty();

Quoted headers aren't picked up if there's an extra line break:

On <date>, <author> wrote:

> blah

Also, they're not picked up if the email client breaks it up into multiple lines. GMail breaks up any lines over 80 characters for you.

On <date>, <author>
wrote:
> blah

Not to mention that we're search for "on" and "wrote". It won't work with other languages.

Possible solution: Remove "[email protected]" lines...

Lines starting with - or _ sometimes mark the beginning of signatures:

Hello

--
Rick

Not everyone follows this convention:

Hello

Mr Rick Olson
Galactic President Superstar Mc Awesomeville
GitHub

**********************DISCLAIMER***********************************
* Note: blah blah blah                                            *
**********************DISCLAIMER***********************************

Apparently, prefixing lines with > isn't universal either:

Hello

--
Rick

To run the test suite, run Composer first to setup the autoloader:

php composer.phar install

Then run the following command:

phpunit
