mb_ereg_replace_callback() is available as of PHP 5.4.1[1]; the 'e'
modifier is deprecated as of PHP 7.1.0[2]. The latter is not yet
documented, though.

Comment for clarification.
Not like preg_replace(), mb_ereg_replace()'s 'e' modifier is specified as
separate parameter. preg_replace() allow to set 'e' modifier in regex and this
made preg_replace() much more dangerous than mb_ereg_replace().
However, callback is much more secure. Therefore, implementation of
mb_ereg_replace_callback() is highly encouraged.

Description:
------------
mb_ereg_replace's e modifier should be deprecated for prevent PHP's code
execution and the explanation for using mb_ereg_replace_callback (since PHP
5.4.1) should be added in the manual.
PHP: code execution via mb_ereg_replace

The reason why preg_replace's e modifier was deprecated in PHP 5.5 can be
applied to mb_ereg_replace's e modifier.
http://www.php.net/manual/en/function.preg-replace.php
https://wiki.php.net/rfc/remove_preg_replace_eval_modifier
There is an example of implementation of mb_ereg_replace_callback as a user
function.
