ok

<?php

error_reporting(E_ALL ^ E_NOTICE);

//error_reporting(E_ALL); // FIXME: kaanna pois paalta

var_dump($_GET);

var_dump($_POST);

var_dump($_COOKIE);

$res_var = @import_request_variables("gpc", "");

if($res_var == false)

	echo "gas";

else

	echo "gassu";

and here's output:

array
'asty' => string 'no' (length=2)
'yrid' => string '' (length=0)
'yid' => string '64' (length=2)
'kirjain' => string '' (length=0)

array
'poista' => string 'KysyPoista' (length=10)
'poista_x' => string '6' (length=1)
'poista_y' => string '6' (length=1)

array
'PHPSESSID' => string '5d2ccf01786dd578b9cb7e3b2362fcbb' (length=32)

gas

so the questin arises: why does it return false?
It does what is asked of it .. all the get/post/cookie variables are converted

Any thoughts ?

Well, it looks like "gpc" isn't a request variable, so it defaults to "" which is interpreted as false.

I don't get it .. gpc = get post cookie
Should be kosher
shouldn't be case-sensitive either

Try adding a prefix and see if that changes anything. Maybe you don't have the most up to date PHP version? It is optional but not suggested so you technically shouldn't be using it anyways.

Of try something like:

foreach($_GET as $id => $key) {
	$pre_$id = $key;
}
foreach($_POST as $id => $key) {
	$pre_$id = $key;
}
foreach($_COOKIE as $id => $key) {
	$pre_$id = $key;
}

Untested but should do the same thing as the function.


Finally a reason for variable variables!!
