I don't actually know what this means: (a) That HTTP_ACCEPT (which is 
the index in the array $_SERVER[] is undefined, or (b) That the value in 
the array is not set... but

Note that this should really be $_SERVER["HTTP_ACCEPT"]

The index to the array is a string. In at least some versions of PHP you 
can omit the quotes, and it will still be interpreted as a string, but 
there is a warning about not doing this with the introduction of defined 
constants (e.g. you'd write define('HTTP_ACCEPT', "HTTP_ACCEPT"); which 
makes HTTP_ACCEPT a _constant_ having the right value. Well if you 
wanted to get confused you would...)

It is _just_ possible that without quotes the interpreter says, ara! 
HTTP_ACCEPT should be a constant, but it isn't defined, so I'll give the 
above error message.

I'm finding PHP an immensely productive way of getting things done, but 
good grief, it's a mess... but here's a mystery:

Can't get this program to run. Whatever I do to try and enable the php 
interpreter, all I get out is the source.
