Maintain PHP4 and MySQL 4.0

[Yeongsik Son]

I'm working at a hosting company, and the company has got lots of clients
who are using PHP4 and MySQL 4.0.
According to the Makefile of mysql40-server, it seems to be ripped out of
4.x, but the clients said they had problems with migrate their databases to
5.x.
Also, PHP 4.x will be supported unitl August 8, 2008 according to PHP.net.
FreeBSD 6 seems to be supported until May 30, 2010, according to FreeBSD
Security Advisory, and I wonder that ports maintainers will continue to
maintain 4.x until that date.
Do they have the plan of estimated EOL of PHP and MySQL 4.x?
If you they got, please let me know about it to force or cooperate with the
clients.
