[RFC] Improved Error Callback Mechanism

Hi Internals, This email is to inform you that Olivier and I have opened for discussion a new RFC in order, for PHP extensions authors, to hook more easily into the default error handler callback: https://wiki.php.net/rfc/improved_error_callback_mechanism There is zero new feature for the users, nor any BC break. The changes made to the engine are for PHP extensions developers changing the behaviour of php_error_cb via zend_error_cb. Currently, supporting multiple extensions that want to hook into it requires very hacky solutions to coexists. We hope this would still be possible for PHP 7.0 as this is only about providing more (useful) hooks and wish we could start voting on it on March 20th. Cheers and thanks in advance, Patrick
