Seems to me that's the case. However the doc is ambiguous, especially as I
*asked* for that key to be returned. IMO it should exist and be empty. Not
existing is only OK if I didn't ask for it.

This is how you tell the difference between a basename with a null
extension ("/path/filename.") and no extension ("/path/filename").
In the former case you get $info["extension"]=>"", in the latter
there is no ["extension"] element in the returned array.
This does seem like the most logical way to make this distinction,
but the manual could use a bit of work to document this and other
edge cases more explicitly.
Cheers!
Mike

OK, this makes sense.

I may have a go at this if I can find a round tuit.

That would be so extreemely inefficient both resources and bandwidth-wise,
however an interesting thought...

Hello, I am just starting out with PHP and I have just created a database named
"Members" with a table named "Persons". There are 5 fields (id,firstname,
lastname, username, password) . The form I created is a sign up form and the
values entered into the form are inserted into the table "Persons", now my
question is how do I create a secure log in system with this new database?
Thanks in advance! :)
