How to remove ppp active connection with php mikrotik api?

I have tried

$api_server->comm("/ppp/active/remove", array( "?name" => $usernametodelete,));

and debug log is :

<<< [18] /ppp/active/remove
<<< [20] ?name=ppp@tunnel.id
>>> [5/5] bytes read.
>>> [5, 1]!done

but ppp user remains active & has no changes
