[PHP] Post 4.1.0 PHP
I've been using PHP 4.0.1 for ages now, and have decided to upgrade one of my machines to 4.2.1 and get used to working under the new security arrangements. I understand that older scripts are fully compatible with 4.1.0+, or can be made so with minimal fuss. I am assuming that scripts written using the new $_GET and $_POST (etc) arrays simply won't run under pre-4.1.0 versions of PHP. So, where does this leave us with regard to ISPs that still run older versions of PHP (so that users' scripts won't break)? Is there some way to write code using the new arrays, but that will run under older versions of PHP. Would including something like this at the top of a script work: $_POST = $HTTP_POST_VARS; while inside the code reference is made only to $_POST ? Sorry if this has been covered repeatedly, I've only just rejoined the list after a break from the relentless volume (of great, useful info).

put that at the of of your scripts and everything will work ok untill you
get things moved over.

RE: [PHP] Post 4.1.0 PHP
The only problem I see with any of these options is that the new arrays
are superglobals (not my term) and do not require the use of the
global command. For instance:
function myfunc() {
global $HTTP_POST_VARS;
$somevar = $HTTP_POST_VARS[somevar];
...
}
can now be written as:
function myfunc() {
$somevar = $_POST[somevar];
}
Sure you can extract the old ($HTTP_) arrays into the new, but you still
don't get the same functionality. (Yes, you could put a 'global
$_POST;' in the new way, but that defeats the purpose of having the new
superglobals)
