input = All
$_SESSION['area'] = $_POST['area'].'<br>'//All
var_dump($_SESSION['area'];//string(7)
var_dump($_POST['area']);//string(3)
Why is like that, why it's varying its length!?
$_POST['area'] is three characters long.
'<br>' is four characters long.
. appends two strings.
$_POST['area'].'<br>' appends a four letter string to a three letter string.
3 + 4 = 7
