Session Handler behaves like object - php

Question

I want to force $_SESSION behave like object using custom session handler. Code as follows,
$_SESSION = [
'user' => [
'id' => '7',
'name' => 'James',
'lastname' => 'Bond',
'login' => '007',
'pass' => 'qwe7fyqw9mhev8qhr',
],
'kill' => [
'Mr_Muscle' => [
'status' => 'alive',
],
'Joe_Black' => [
'status' => 'dead',
]
],
];
$session = new Session();
echo $session->user->name;
$session->kill->Mr_muscle->status = 'dead';
$session->save();
I did it almost but I get warning:
Warning: Creating default object from empty value in /var/www/project/mvc/bootstrap.php on line 80
when I'm trying to create new value, in this case:
$session->kill->Dr_Quinn->status = 'dead';
Value will be created but I don't want to hide this warning, I want to do away with it.
class Session
{
public function __construct()
{
foreach ($_SESSION as $key => $value)
{
$this->{$key} = $value;
}
}
public function __set($name, $value)
{
$this->$name = $this->arrayToObject($value);
}
private function arrayToObject($array) {
if (!is_array($array)) {
return $array;
}
$object = new stdClass();
if (is_array($array) && count($array) > 0) {
foreach ($array as $name=>$value) {
$name = strtolower(trim($name));
if (!empty($name)) {
$object->$name = $this->arrayToObject($value);
}
}
return $object;
}
else {
return FALSE;
}
}
public function save()
{
$_SESSION = json_decode(json_encode(get_object_vars($this)), true);
}
How to fix it?

Answer 1

Just do
if (!isset($session->kill->Mr_muscle))
$session->kill->Mr_muscle = new stdClass();
$session->kill->Mr_muscle->status = 'dead';
to avoid this warning.
