Question

I am getting problem while using fwrite in php. the following code works in my local computer but gives error in server.

$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if(!$fp) {
   echo 'Error: '.$errno.', '.$errstr;
} else {
   fwrite($fp, 'kool');
}

There is no error with fsockopen. it passes and gives no error. fwrite is not being able to write. it fails and returns no error only false

If you’re on a shared host, most likely your server does not allow outbound connections on port 80. Usually only inbound connections are allowed.
