 You were right to some extent.  However, the problem is more
complicated (or less complicated, depending).

First, FreeBSD's default php.ini doesn't have:

$variables_order = "EGPCS", so $ENV[] array wasn't getting popualted at

Second, Apache FreeBSD RC scripts inherit the user environment from
sudo(8) unless you pass -H or -i flag/args


 % sudo -H -i -u root /usr/local/etc/rc.d/apache22 restart

Compared to:

 $ su -
 $ /usr/local/etc/rc.d/apache22 restart

Result in completely different results in PHP's $_ENV[]

Additionally, the results of "$ su -" differ completely from the shell
environment that executes when rc(8) is first run at boot time.

I may be better off using getenv() in PHP directly.
