On my homepage, I have five 'require_once' calls and within one of
those, two more 'require_once' calls. I want to increase this from
those seven to about twelve. This seems like no problem but I'm
wondering what the most anyone else has tried without any costly
degradation of load time.
Thanks a bunch.

To be more specific, what I want to do is include other php files to
make up my sidebar based on which page I'm calling from. For example,
I don't want to include a link to our schedule of speakers if that is
the page that I am on. Would a case statement be the best way to
handle this?
p.s. if not obvious, I'm a php newbie.

Every 'require_once' requires the server to open that (php-)file.
This should normally not be a problem, because if you have enough
memory, and the file is used often enough, the contents of this file
will be cached.
You should, of course, only 'require_once' files that you really need,
and skipp files that you do not need.

chances are it will all be cached in RAM anyway.
So not much...

why not?

sure - make a generic 'sidebar' file and selectively omit bits of it
depending on a paraetr passed to your 'draw_the_sidebar($for_this_page)
function

with respect, a coding newbie. That's basic coding approach stuff. In
any procedural language.
first of all you learn inline code.
You discover you are writing the same bit over and over.
You invent the macro or the subroutine (function)
You discover you are writing subroutines that are almost the same as
each other.
You invent the subroutine whose behaviour varies according to parameters.
You discover lots of these subroutines can be used by different programs
You invent the library, included or linked or run time linked...

The increase in load time will be entirely lost in comparison to the
amount of time it takes to shove all the bits half-way around the world
to someone's browser.

Shouldn't be a problem. In my scripts there can be several dozen classes
be required in order to answer a single page request, all loaded from
separate files. But most of them will be cached, either by the OS or by
a bytecode cache in PHP, so it's not really a problem.

Impossible to answer. require_once or all the other PHP ways to execute
another script is not the point (the statement is pretty cheap), the
important value is how the actions taken in the required scripts scale.

Thanks for your reply (and all others). What would be an example of
poor scaling? Mostly, my php amounts to 'require_once' and a few
calls for "Last modified' date, passing the 'title' and obtaining
today's date. Pretty simple so far.

When the server gets too overloaded to handle the requests it the time
to worry about performance. And then you need to look at what's
actually causing the performance problem.
Including or requiring files is going to be one of the least of your
worries.
And being concerned about it when you have no problem is just premature
optimization. Rather, build your code where it is maintainable and
understandable.
