[tony007]

Hi all i want to write a php script that if only the request came from media player it work other wise it gives an error massage .for example if the request came from get or post or direct url execution in browser addrres i want it to send error message. I be happy if some one show me how to check for media players. I just do not know how to check for agent.Thanks

if($_SERVER['HTTP_USER_AGENT']=="your_user_agent") 
{ 
    //load your file 
} 
else 
{ 
    //load the error message 
}

Using the user agent field is always a bit flaky, but you could try this

$ua = $_SERVER['HTTP_USER_AGENT'];

if (strpos($ua, 'Windows-Media-Player') || strpos($ua, 'NSPlayer')) {
  // Windows Media Player
}
else if (strpos($ua, 'RealMedia')) {
  // RealPlayer
} 

I don't know of any more unfortunately.
