PHP Question

Determine in php script if connected to internet?

How can I check if I'm connected to the internet from my PHP script which is running on my dev machine?

I run the script to download a set of files (which may or may not exist) using wget. If I try the download without being connected, wget proceeds to the next one thinking the file is not present.

function is_connected()
    $connected = @fsockopen("", 80); 
                                        //website, port  (try 80 or 443)
    if ($connected){
        $is_conn = true; //action when connected
        $is_conn = false; //action in connection failure
    return $is_conn;
