README

Email\Parse is a multiple (and single) batch email address parser that is reasonably RFC822 / RFC2822 compliant.

It parses a list of 1 to n email addresses separated by space or comma

Installation:

Add this line to your composer.json "require" section:

composer.json

    "require": {
       ...
       "mmucklo/email-parse": "*"

Usage:

use Email\Parse;

$result = Parse::getInstance()->parse("a@aaa.com b@bbb.com");

Notes:

This should be RFC 2822 compliant, although it will let a few obsolete RFC 822 addresses through such as test"test"test@xyz.com (note the quoted string in the middle of the address, which may be obsolete as of RFC 2822). However it wont allow escaping outside of quotes such as test@test@xyz.com. This would have to be written as "test@test"@xyz.com

Here are a few other examples:

"John Q. Public" <johnpublic@xyz.com>
this.is.an.address@xyz.com
how-about-an-ip@[10.0.10.2]
how-about-comments(this is a comment!!)@xyz.com
