Php 7 Support Dropped

As of mail-mime-parser 3.0, support for php 7 has been dropped.

New in 3.0

Most changes in 3.0 are 'backend' changes, for example switching to PHP-DI for dependency injection, and basic usage should not be affected.

The header class method 'getAllParts' includes comment parts in 3.0.

Error, validation, and logging support has been added.

For a more complete list of changes, please visit the 3.0 Upgrade Guide and the Usage Guide.


MailMimeParser requires PHP 8.0 or newer. Tested on PHP 8.0, 8.1, 8.2 and 8.3.
