Testing for an internet connection

[MrBelfry]

Hey

I'm developing a couple of scripts to serve as an intranet. Some of the scripts allow the user to update a db on a remote server BUT as we're on dialup I wanted to check to see if there is an internet connection available before I give them the option. My feeble newby mind has come up with this:

if(@fsockopen('[URL unfurl="true"]www.google.co.uk',[/URL] 80, $errno, $errstr, 10)) echo 'connection available'; else echo 'connection not available';

But I'm wondering if there is a better way?

Are you running php on a local web server or is the php a command line program?

MrBelfry:
fsockopen() is probably a good way to check.

Just keep in mind, however, that using a URL rather than a quad-dotted IP address as the target of your fsockopen() invocation not only checks for the existence of a connection to the internet, but also requires that your DNS system be working correctly.

PHP running on windows and apache

Thanks for the tip sleinir I'll change the URL to an IP address.
