ColdFusion and PHP variables

I am looking to port some application code from PHP to ColdFusion

ColdFusion Variables:

variables.*
request.*
session.*
application.*
server.*
form.*
url.*
arguments.*

PHP variables

$something

$_POST['something']
$_GET['something']

function getSomething($something){   
global $someglobal;
$something
...

Here are the available scopes in ColdFusion with their appropriate PHP counterpart to the right:

If you use a variable name without a scope prefix, ColdFusion checks the scopes in the following order to find the variable:

Local (function-local, UDFs and CFCs only) => No array.

Arguments => ?

Thread local (inside threads only) Query (not a true scope; variables in query loops) => ?

Thread => ?

Variables => $GLOBALS[]

CGI => $_SERVER[]

Cffile => $_FILES[]

URL => $_GET[]

Form => $_POST[]

Cookie => $_COOKIE[]

Client => ?

Request => $_REQUEST[]

Here are the pages where I would use to reference:

http://php.net/manual/en/language.variables.superglobals.php

I don't do ColdFusion, but I can hazard some guesses based on this documentation.

For starters, PHP doesn't classify its variables explicitly by scope.

variables.*

...is just $var1 or $foo or whatever. It's scoped depending on its location - is it in a function, a class, free, etc.

request.*

These are apparently "non-persistent global variables" which are probably $_GET[] and $_POST[] (both arrays) in PHP.

session.*

That's an easy one. $_SESSION.

application.*

This is probably best approximated by $_SERVER.

On that page are several other variable types that will probably answer your question. Be wary, though, in PHP global variables are a quick invitation to security holes.
