Hi all.
I'w writing a PHP app that is designed to run over a LAN, so internet connection for the server is not really essential. Some users may deliberately not connect it to the internet as a security precaution.
But I'd like the app to make use of an internet connection if it exists to check for an update, and notify the user.
Is there a simple way for a PHP script to check if it has an internet connection?
I thought of this :
if(fsockopen("www.google.com", 80)){
// we are connected
}
Is this OK or is there something better for the purpose?
