Although I do agree that you can do everything without using bit
operations, and a few bitwise operators here and there are not going to
make your code ultra fast.  I still see value in using them.

Clean Code:
In the example I demonstrated, I find it actually keeps the code simple,
clean, and easy to read.  For example, If I was to track those flag
values as booleans, I would want to aggregate them all in another data
structure such as an array or object.  With this comes more code and
complexity.

Speed:
Php is parsed at runtime (aside from code accelerators/caching).  Even
if you have a fast processor(s), there still is alot that happens every
time a php script is requested.  If you can replace arrays of options
with a few bitwise operators, it may not be much, but it's gotta do
something. ;)

Just my opinion.
