Variable declarations

[Mike]

Hello,(Im not getting any help from the other php groups)
I am studying the install/install.php file from phpBB(Forum
Software).This is the first
file called when installing phpBB.What I don't understand is the fact that
the variables are RETURNED before they are initialized.
Line 33:
<meta http-equiv="Content-Type" content="text/html; charset=<?php echo
$lang['ENCODING']; ?>">
Line 299-302:
// Initialise some basic arrays
$userdata = array();
$lang = array();
$error = false;
If you would like I can post the file so you don't have to look for it.
Thanks
Mike

Not having the files handy, I'm guessing that they have an include() or
require() statement somewhere that defines $lang...

Dont know why you posted these here... just sets $userdata to be an array,
and sets $lang to be a new array (or, perhaps resets it to be a blank array
if it was already defined in an include() somewhere...)

Not quite sure what the question is, to be honest. And I don't see any
return statements anywhere in what you posted.
