The question is not one of performance since while it will be quicker to
call a function than include a file the difference is going to be
inconsequential.
If you were to use a function where would you put it? You imply it needs
to be used from multiple scripts, so it would need to be in an included
file anyway which makes the question kinda pointless.
Whether to use a function should then be based on how you need to use
this "block of text". Will it be used more than once in any given
script? If yes then you want a function so you only need to include the
file once. If not then it really doesn't matter whether you use a
function in the external file.
When you're thinking about possible performance issues there are two
things you need to ensure...
1) You're not spending time optimising the wrong bit (this would be an
example of that). You can check that by writing a quick performance test
as someone did later in this thread. 90% of the time you'll find that
the performance difference between two options is negligible.
2) The architecture and maintainability of your code is more important
than most performance issues you can imagine.
Performance optimisation should be driven by performance problems. Write
your app, test it, find bottlenecks and then optimise those. Time spent
saving 0.001 seconds per request is better spent elsewhere.

I just started using PHP and got to think...
Without getting into the discussion of "best practices", strictly
from a performance perspective,
what is faster: a function or an include?
For example I have a block of text that needs to appear mutliple times
throughout the site.
Will I be better off creating a function with its contents and then
later just calling the function or,
will it be faster (from an execution perspective) for me to create an
.inc file that gets included later on?
Thanks for the your thoughts.
