[mlmmj] [PATCH] ereg() removed in PHP 7.0

[mlmmj] [PATCH] ereg() removed in PHP 7.0

[-- Attachment #1.1.1: Type: text/plain, Size: 735 bytes --]

Debian is transitioning from PHP 5 to PHP 7.0, and PHP 5 is soon to be
removed.  The current mlmmj PHP code has 2 to calls to ereg() functions
which were deprecated in PHP 5.3.0 and removed from PHP 7.0.0, thus
requiring modification.  Attached is a patch that does this.

Note that the regex in contrib/web/php-user/mlmmj.php for matching email
addresses could also use updating to allow for the full range of special
characters that are allowed in email addresses:

   https://tools.ietf.org/html/rfc5322#section-3.4.1

Right now it looks like these special characters might not be accepted by
the regex AFAICT:
   ! # $ % & ' * + / = ? ^ ` { | } ~

Thanks

   https://secure.php.net/manual/en/function.ereg.php
   https://secure.php.net/manual/en/function.eregi.php
 Also remove min 2, max 4 character TLD portion of regex, as there are
 top-level domains > 4 chars now.
 Thanks to Ron Guerin <ron@vnetworx.net> for his help with the PHP regexes.
