Session properties always return true if the properties is empty

[ebauger]

Hi,

I use this stack for my Slim v4 API:

composer.json I use:

{
    "require": {
        "php": "^7.3",
        "slim/slim": "^4.3",
        "slim/psr7": "^0.6.0",
        "bryanjhv/slim-session": "^4.0"
      }
}

In my route function

// [...]
$session = new SesssionHelper();
$session->my_key = ''; // empty string
isset($session->my_key) // return true // expected true
empty($session->my_key) // return true // expected false
// [...]

Someone can replicate and validate this result?

Please explain why you expect empty() to return false when given an empty string.

Oups my mistake. Thank for your answer. expected is true not false.
