Thanks, but most variables such as SERVER_ADDR and SERVER_NAME are not set
when you run a PHP script from the command line (or from cron). Write a
script that calls phpinfo() and then use 'php -f' to run it and you'll see
how little environment information you get.

Why just not use the built in variables:
$SERVER_ADDR
$SERVER_NAME
not that tough, :)
