[New API] Create a temporary Config instance

Hi
I want to create a temporary Config instance without saving the file. Is it possible?
I tried with:

PHP:

$cfg = new Config(null, Config::YAML);
$data = array("temp" => "test");
$cfg->setAll($data);
//Then
echo $cfg->get("temp");


This code works but it generates a File not found error
Is there a better way to do this without get the error?

What about "/dev/null" (for Linux only)?

And what about "php://tmp"?

Actually, why do you even need it? Why not just use an array?

Yes it's better. I wanted to do this only to keep PocketMine Config class functions

Create your own class...
