Codeigniter development (v3.0)

[eluser]Florian Müller[/eluser]
As I heard here, the new CodeIgniter-Version may also contain a switchable Session class which allows the user to determine wether to use cookies or native PHP sessions. How will this be done?

Another thing I found quite hard in CodeIgniter is handling statuses. CodeIgniter does expect to return a method true on success or false on failure. If I want to return a status, I actually only can return a string or a number. I solved this with Pseudo-Enums, e.g. the following:

Code:

<?php
class StatusEnum {
    const FAILED_NORIGHTS = 1;
    const FAILED_UNKNOWN  = 2;
    const SUCCESS         = 3;
}
?>
...
<?php
$res = $class->myFunction();
if ($res == StatusEnum::FAILED_NORIGHTS) {
    echo "no rights";
}
?>

I don't know if this is common, but it's a very nice way to handle statuses in frameworks where even the exceptions are not thought of this (exceptions in CodeIgniter are meant to display a page or something, but only used if a real error happened).

What do you think of this last proposal? I think it would be worth an analysis

And, my last question: Is there somewhere an assessment when CodeIgniter v3.0 will be available?
