EncodeQPphp() in https://we.phorge.it/source/phorge/browse/master/externals/phpmailer/class.phpmailer-lite.php$1495 is while( list(, $line) = each($lines) )
each() has been DEPRECATED as of PHP 7.2.0, and REMOVED as of PHP 8.0.0 per https://www.php.net/manual/en/function.each.php
FYI the class is called in several places:
./phorge/src/applications/metamta/adapter/PhabricatorMailAmazonSESAdapter.php: require_once $root.'/externals/phpmailer/class.phpmailer-lite.php'; ./phorge/src/applications/metamta/adapter/PhabricatorMailSMTPAdapter.php: require_once $root.'/externals/phpmailer/class.phpmailer.php'; ./phorge/src/applications/metamta/adapter/PhabricatorMailSendmailAdapter.php: require_once $root.'/externals/phpmailer/class.phpmailer-lite.php';
Same issue for https://we.phorge.it/source/phorge/browse/master/externals/phpmailer/class.phpmailer.php$1627
