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.
This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 4.2.0.
