1.) $_FILE is the global variable defining uploaded files, see:

http://us3.php.net/features.file-upload

2.) When you talk about a period (".") I'm guessing you mean like used in the following:

PHP:

<?php
$string1 = $variable1 . ' means something';
?>

Where the period is a string concatenation operator, which means that that the period joins more than one strings.

Here is the way I understood it.

PHP:

<?php

$a = 'Hello ';
$b = $a.'Canada';

?>

If you're talking about in reference to files and filesystems, '.' = current directory i..e 'cd . ' would put you in the current directory or './file' woudl give you that file in this directory, whereas '..' is the directory immedialty before your current directory.

if you have this dir structure

-dir1 (/dir1, or ../dir2 or ../dir3)
-------dir2 (/dir1/dir2)
-------dir3(/dir1/dir3)

if you're in dir2, then ../ would put you in dir1 and ../dir3 would put in dir3

if you're in dir2 or dir3 then cd ../ will put you in dir1.
Got it?

also next time. use a more descriptive title. dont put "php question" or "noob learning" put "Description of $_FILE and . " that way if someone looks at the title and gets the feel for what the topic is about. you will get better help. because when i saw your post, i didnt wanna look at it at all, but being a mod and all i guess i had to...
