Some languages allows to bit-pack structures to save spaces. Since PHP
doesn't have native set data type and operations, will array of booleans be
optimized as such? If not, how can I achieve the same result? I need to save
about 200 boolean values and I guess it's a good idea to use bitsets.
Requirements:
- Easy to use (set, unset, test), so C way to use bitwise operations is
simply rejected.
I need something like Pascal's set.
- Small space (bit level if possible)
