Well, it can easily be changed by the user - being a parameter to the
URL. And if you use:
include ('http://...);
You're making another call to the server, getting it to access and parse
the page and return the results to your current page. If it's a remote
system, you'll probably have to do that. But it's a waste to be doing
it to your local system. Just including the file with:
include ('/path/to/file...');
is much more efficient. Additionally, you get the unparsed page (i.e.
PHP code) which can be executed here, instead of the html output by the
server in the previous include.
And btw - when you do use the first include, you have to make sure you
remove out all of the extra tags, such as DOCTYPE, <head>, </body>, etc.
from the included file output to ensure you are sending valid html to
the client.
