php Authentication script?

Hi,

I used to run stream via icecast streaming server which had php authentication capabilities.

My question is, is it possible to do the same with FMS? Put this sort of code in main.asc to verify a viewers credential before allowing him to watch. At the moment the domain/swf restrictions work well but this could add a little more security into the mix?

Something like this to determine whether a user has an active subscription to watch a certain video

<?php

function MySQLConnect( )

{

$db_host="localhost";

$db_username="xyz";

$db_password="xyz";

$db_name="xyz";

$connection= mysql_connect( $db_host, $db_username, $db_password );

if (!$connection)

        { return "FAILED"; }

mysql_select_db( $db_name, $connection ) or die ("FAILED");

return $connection;

}

function basic_icecast_check_user_allowed ( $username , $password  )

{

$allow_user_auth_query = "

select

xyz_members.login,

xyz_members.pass

from

xyzr_members,xyz_payments

where

xyz_payments.member_id=xyz_members.member_id and

xyz_members.status=1 and

xyz_payments.expire_date>NOW() and

xyz_members.login='$username' and

xyz_members.pass='$password'

limit 1                        "

$find_allowed = mysql_query ( $allow_user_auth_query );

$auth_stream_count = mysql_num_rows ( $find_allowed );

if ( $auth_stream_count==0 )

        { return array(0,"User Invalid",0); }

$test_allowed = mysql_fetch_assoc( $find_allowed );

if ( $auth_stream_count==1 )

{

return array(1,"Found",0 );

}

return array(0,"Password Invalid",0);

}

?>
