PHP server IP script

[The Titan]

Im just going to start from the beginning for this one ;)

Ok, I have a domain name hosted by a 3d party. I also have a sorry home server that as a use as a testing environment, The problem is i have a dynamic IP.

Is it possible to make a script (cron job maybe?) that gets my ip from the internet and send it to the domain with a form? I can do any scripting in PHP or do forms but i dont know how to get my server IP.

If this is confusing, or you need more information please tell me.

Thank you,

You could try


$_server['server_ADDR'];

Thank you for that, How would i go about running that PHP script every 5 minutes? Could i use a CronJob? I've never used them before.

I have never used PHP-CLI before but my guess is yeah you could use it as a cronjob. Im pretty sure there is a tutorial around here that tells you exactly what to do.

...or you could use dynamic DNS which would accomplish the same thing and probably be easier to set up

Yea dynamic dns would work better. I have these script on my site that work on ubuntu.

<?php

Some home routers have ddns built in. You just have to tell the router your login info and it will keep your dynamic domain's host up to date with your IP.

I know Rosewill and D-Link routers come with this.

Here's the biggest ddns provider:

Its a free service for a subdomain.
