Hi,

I have recently installed PHP 4.1.1 and I found
that _POST is not a reference of HTTP_POST_VARS
but a copy. I think that it should be reference.


Here is a reply to one of my old message in which
Yasuo Ohgaki wrote:

A simple script for prove:

<?php

function func_change(&$value, $key)
{
	if (is_string($value)) {
		$value = '***'.$value;
	}
}

echo('<PRE>');
echo('HTTP_GET_VARS before: '); print_r($HTTP_GET_VARS);
echo('_GET before: '); print_r($_GET);

reset($HTTP_GET_VARS);
array_walk($HTTP_GET_VARS, 'func_change');
reset($HTTP_GET_VARS);

echo('HTTP_GET_VARS after: '); print_r($HTTP_GET_VARS);
echo('_GET after: '); print_r($_GET);

echo('</PRE>');
?>


call it as:
/testsuperglobals.php?x=lalal&a=1&b=dkdkkd

and you will see this:

HTTP_GET_VARS before: Array
(
    [x] => lalal
    [a] => 1
    [b] => dkdkkd
)
_GET before: Array
(
    [x] => lalal
    [a] => 1
    [b] => dkdkkd
)
HTTP_GET_VARS after: Array
(
    [x] => ***lalal
    [a] => ***1
    [b] => ***dkdkkd
)
_GET after: Array
(
    [x] => lalal
    [a] => 1
    [b] => dkdkkd
)
