Any assumptions I made regarding your level of experience came from this

[I would personally go with "let's either find out or make a decision"
instead of wasting time on coding for situations that will crop up.]

Aside from the presumably erroneous use of "will" instead of "may", this
suggests to me that you are the type of developer who writes code in the
quickest way possible without any concern for its quality or its use beyond
your involvement. Maybe I'm wrong, but I can only go by the evidence that's

My primary point was that you have not removed assumptions. You may think
you have by putting restrictions on the environment in which your code runs,
but as I said earlier, the larger a project becomes the less likely it will
be that those conditions are going to remain in place. So, those
restrictions are essentially assumptions.

No piece of software would ever get finished without assumptions being made
or various restrictions being in place, but it's always a compromise between
cost of mitigation now against the cost of dealing with changes in the
future (the 10%/90% I mentioned earlier). On that basis I see huge value in
normalising and centralising the generation of URLs for any project that
consists of more than a few simple PHP pages.

Anyway, I doubt there's much point in continuing the conversation -

Your role in my world is simply that if your responses in this thread
reflect how you approach your software development, unless you say or do
something that changes my view of that approach I would probably avoid ever
working with you, or on any software with which you've been involved.

This was fun... we should do it again sometime! ;)
