Hello,
I've done some homework on my own by reading through PHP documentation and
various articles; however, I am still a bit confused as to what is supported
in PHP 5.0 when register_globals is set to off.
In PHP5.0, if the register_globals parameter is set to off (as it is by
default), I know that we're supposed to use the $_POST super globals to
access the post variables. My question is, is the $HTTP_POST_VARS global
still populated for backwards compatibility? In other words, if I have an
old script that has the following piece of code running on a PHP5.0
environment with register_globals off (after submission of a form), would it
still work as expected?
Function someFunction($variable) {
global $HTTP_POST_VARS;
return IsSet($HTTP_POST_VARS[$variable])
}
Thanks in advance for your help.
