PHP Error

Look at the code first.

runs normal win5.3.13 on the local side. There are no errors.
But there was an error on the server side. (I don't know what the server-side settings are.) ) linux5.2.8
Parse error:syntax error, unexpected t_string in/home/xxxxxxxx/emailreturn.php on line 2
and then I tasted it on the server side. Try the code a bit.

!--? php header (' content-type:text/xml '); Echo ' 
    !--? php echo $code,?-->!--? php if (isset ($message)):?--> 
    
     !--? php echo $message;?--> 
    !--? php endif;?--  

The server is functioning normally. What is wrong with this, and why did you find this error?
