Information about the remote server (php, fsockopen)

[lan-online]

Hi!

 

Is it possible to get information about the server through PHP fsockopen ?

 

What is a request to write to the socket?

 

For MC

fwrite($fp, "\xFE\x01");

 

For CS

fwrite($fp, "\xFF\xFF\xFF\xFFTSource Engine Query\x00");

 

For PZ

fwrite($fp, " ??? ");

 

Any other way to get Information about the remote server?

 

Thanks for help.
