if we use this one
if(fopen("http://www.ntc.gov.au","r";))
{
echo "success";
}else
{
echo "false";
}
result is false.

with fsockopen, we can ONLY check "www.ntc.gov.au", and we can not
check if the whole url is reachable or not.
It seemed that fsockopen is only valid to check host name, while not
the whole ip string.

Any good idea to check the who ip string instead of just host name?

thanks.

That's because you need to send the request using HTTP headers (if trying to communicate with a Web server). Also, you're checking if a resource exists on a server, you're not checking an IP address. www.ntc.gov.au is a domain.

You should become best friends with Google for a while.
