check internet connection

[peteraub]

I am building a desktop application using php and mysql database. Some functions need to be done online while others dont need internet connection. The users use dial up connection.

I was wondering if there is a way I can determine if users are connected to internet to warn them before they use online functions.

You could try to pull an online file for example:

if ( fopen("www.phpbuilder.com", "r"); ) {} else { print "Sorry but you must have a connectionto the internet to perform this function. }

Hope this helps!

Tweaked it for ya, should work straight out of the box as long as phpbuilder is online.

<?php

if ( @fopen("http://www.phpbuilder.com", "r") ) 

{} 

else 

{ print "Sorry but you must have a connectionto the internet to perform this function."; } 

?>
