getting vars from $_SESSION throws an error

while passing $_SESSION['var'] to function, if $_SESSION['var'] is unset, I'm getting Notice: 

Notice: Undefined index: var in scripname.php on line 49

Is there safer way to obtain $_SESSION['var'], which will give me 0 if $_SESSION['var'] is unset?

Thank you in advance!!

if(!array_key_exists('var',$_SESSION))
{
    $var = 0;
}
else
{
    $var = $_SESSION['var'];
}

How about:

$var = @$_SESSION['var'];
