Empty doesn't work on session data

[LostKobrakai]

Hi there,

is this a behavior of "$session->data" a lack of my php knowledge or is this a bug, that empty() returns false?

var_dump($session->successmsg);
var_dump(!empty("Erfolgreich! Ihnen wurde eine Email mit den Download links zugeschickt.;"));
var_dump(!empty($session->successmsg));
$tmp = $session->successmsg;
var_dump(!empty($tmp));

Output: 

string(72) "Erfolgreich! Ihnen wurde eine Email mit den Download links zugeschickt.;"
bool(true)
bool(false)
bool(true)

Greetings,

Benjamin

$sesion is a wrapper for the native session.

One of the good things is you don't need to do isset($session->data) but just

if($session->data) ...

If it doesn't exists or is empty it will return NULL.

So it was my lack of php knowledge .

I set it to "" at the beginning of my formvalidation and I thought it would be nicer to read this way, instead of "if($session->data != "")"

WillyC is right

Another example that does not work with magic getters:

$arr = array(1,2,3);
$session->arr = $arr;

// Does not work!
echo $session->arr[1];

// To echo out array elements, do this
$arr = $session->arr;
echo $arr[1];
