Hello !
I’m currently working on the Hoa Project (http://hoa-project.net) about
a `glob` behaviour integration:
https://github.com/hoaproject/File/pull/22
We found that there are some difference between the `glob` function and
the
`GlobIterator` object.
1. `glob`
This function is able to scan only dirs with the GLOB_ONLYDIR constant
and is also able
to expand braces to match in a list of items with GLOB_BRACE.
Exemple with glob(‘/{a,b,c}/foo/bar’, GLOB_BRACE), it’ll search :
- /a/foo/bar
- /b/foo/bar
- /c/foo/bar
2. `GlobIterator`
This object has no options or constants to apply the same logic than
GLOB_ONLYDIR and GLOB_BRACE.
It’s possible to combine different iterators and obtain the same
result but it’s a lot more
complicated.
Exemple with new GlobIterator(‘/{a,b,c}/foo/bar’), it’ll search :
- /{a,b,c}/foo/bar
Is there some reason about the differences in these two implementations
?
I found that the braces expansion is not part of the “official” glob
pattern definition but
it’s definitively an awesome feature.
Thanks in advance for your attention.

By no means do I pretend to have any insight to the internals of PHP,
but if I
were to take a guess, I would say that the functionality of the glob was
initially
modelled after the glob'ing ability found in most all *nix cli tools
from years
past.
