Bug Type: Documentation problem
Operating System: Windows XP
PHP Version: 4.2.1
New Comment:
Using import_request_variables() is close, but since it became
available in PHP 4.1.0 it's not ideal, and it only deals with GPC.
Using extract() will be closer, something like:
// register a lot of vars if register_globals = off
if (!ini_get('register_globals')) {
$types_to_register = array('GET','POST','COOKIE',
'SESSION','SERVER');
foreach ($types_to_register as $type) {
if (@count(${'HTTP_' . $type . '_VARS'}) > 0) {
extract(${'HTTP_' . $type . '_VARS'}, EXTR_OVERWRITE);
}
}
}
This does not rely on the variable_order directive, which I prefer not
to do, but it could :) Maybe someone wants to add ENV, or subtract
some, or add a prefix. All possabilities to think about.
Also note that default for register_globals became "off" in PHP 4.2.0
but as of PHP 4.1.0 it was recommended to have it off.

I was a bit surprised as well, as there were no hints on making old
scripts compatible to PHP's new behaviour. In fact, a simple
import_request_variables("gpc"); inserted somewhere at the beginning of
your script (usually every script has a config.php, which is included
by all other files) would be a good workaround until these scripts are
rewritten to "register_globals=off".

The intro tutorial says the following:
One of the most powerful features of PHP is the way it handles HTML
forms. The basic concept that is important to understand is that any
form element in a form will automatically result in a variable with the
same name as the element being created on the target page.
But it is not true any more, since the global variable is turned off by
default since 4.1.2 and it is said that it is bad practice to turn it
on.
There are so many new PHP programmers who stumbled on this one. The
scripts they write according to the tutorial simply do not work.
Also, there are a lot of scripts written before 4.1.2 that use this
feature and they won't work after being downloaded by people who are
not familiar with PHP.
