I have this code I made:

 <?php

 $to = "example@random.co.uk";
 $$subject = "Email";
 $message = "
                Hi, Dave!
 ";

 mail($to, $subject, $message);

 ?>

It works fine in Chrome, but in Opera, it is obsolete. Can anyone tell me why? I thought PHP processes on the server, not the client.

PHP is processed server side. So the browser will only affect what input is sent to the server.

Perhaps if you expand upon what isn't working, that might shed some light on the issue.
