PHP runs on the server, and can't know whether a client has loaded a page into
a frame or somewhere else, so your ordering of events isn't quite right.
PHP can itself read a remote page (see file_get_contents(), and fopen_wrappers
which allow the filesystem functions to transparently read URLs - this is
enabled on most configurations), process it, and then output that page (with
whatever modifications are appropriate) - you then arrange that this PHP script
is what is loaded into a particular frame.
