The cleanest way would to post to the webserver requesting the information; Something serverside.
something maybe like..
Code:
Public Shared Function RetrievePlayers() As String
Dim webclient As New WebClient()
Dim Response As Byte()
Try
webclient.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
Response = webclient.UploadData("http://127.0.0.1/PLAYERCOUNT.php", "POST", new Byte())
webclient.Dispose()
Catch ex As WebException
webclient.Dispose()
Return "error"
End Try
Return System.Text.Encoding.ASCII.GetString(Response)
End Function
Then you could do a server-side php script that just read up the players or whatever you'd like to do, and then echo it.
