EmailReplyParser is a PHP library for parsing plain text email content, based on GitHub's email_reply_parser library written in Ruby.

The recommended way to install EmailReplyParser is through Composer:

composer require willdurand/email-reply-parser

Instantiate an EmailParser object and parse your email:

<?phpuseEmailReplyParser\Parser\EmailParser; $email = (newEmailParser())->parse($emailContent);

You get an Email object that contains a set of Fragment objects. The Email class exposes two methods:

• getFragments(): returns all fragments;
• getVisibleText(): returns a string which represents the content considered as "visible".

The Fragment represents a part of the full email content, and has the following API:

<?php$fragment = current($email->getFragments()); $fragment->getContent(); $fragment->isSignature(); $fragment->isQuoted(); $fragment->isHidden(); $fragment->isEmpty();

Alternatively, you can rely on the EmailReplyParser to either parse an email or get its visible content in a single line of code:

$email = \EmailReplyParser\EmailReplyParser::read($emailContent); $visibleText = \EmailReplyParser\EmailReplyParser::parseReply($emailContent);

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 

The above On ....wrote: can be cleaned up with the following regex:

$fragment_without_date_author = preg_replace( '/\nOn(.*?)wrote:(.*?)$/si', "", $fragment->getContent() );

Note though that we're search for "on" and "wrote". Therefore, 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 ________________________________________ From: Bob [[email protected]] Sent: Monday, March 14, 2011 6:16 PM To: Rick 

Setup the test suite using Composer:

$ composer install 

Run it using PHPUnit:
