question regarding syntax style in form variables

[thosecars82]

I have read that there are 3 choices of syntax style for form variables depending on the php version you are running and depending on how is your register_globals parameter set:

$variable

$_POST['variable']

$HTTP_POST_VARS['variable']

I would appreciate if anybody could tell me where i can find and modify this parameter manually to activate each of these choices of syntax. Moreover, I think it might be useful to be able to decide dynamically the type of syntax you must use in your code to access form variables. Furthermore, this would make it easy to migrate the code between different php versions. I guess developers will use something like this, right? For that reason it would be great if somebody could tell me if there is an easy way to do it.

With any except the most extremely out-of-date PHP installation, you can count on $POST['variable'] to work. $variable will only work if the now-deprecated [man]register_globals[/man] option is enabled (and which will not be available at all in PHP 6), and the $HTTP_POST_VARS option should only be needed if using a PHP version older than 4.1.0, and it is not "super-global" as $POST is.
