[PHP] Re: Can someone explain this please...
Hummm, sorry, you're right, you're converting it do a "fake" octal via
strings, I was wrong in my first paragraph. In any case, if it helps, on
my comp it really does evaluate true.

Hi!
I don't know why it doesn't because it really should ALWAYS evaluate
true with your code, regardless of absolutely anything.
The reason is that the quoteless 777 you're comparing to is in decimal
and it would defy math if you were ever able to get $perms==777. Anyway,
it does evaluate true on my computer and does delete that dir.
You might want to try this:
Please be aware though that in typical conditions your permissions are
masked, therefore you're not going to be able to create directories with
0777 permissions via PHP without tweaking your PHP config.
