So I have this two option to use:
$_SESSION["select_hero"] = mysql_real_escape_string($_POST["select_hero"]);
$_SESSION["select_hero"] = isset($_POST["select_hero"]) ?
mysql_real_escape_string($_POST["select_hero"]) : "";
In this case let's say that a user can choose between one heroes using a radio button. I do not 100% understand what is the point/difference between this two Sessions.
Thx for any help with understanding..

The later checks first if the variable is POSTed before assigning it, this is actually a good thing, as newer PHP would generate warnings on the first approach if the variable isn't set from the form.
