PHP break not working

I am trying to disable a form on weekends. In my code I have a break after the variable $noaccess. When I run the code the form does not load. I am not sure what is going on please help. Here is my code:

$wkday = date('D');
if ($wkday == "Sun") {
            $noaccess = "yes";
            break;
} elseif ($currday == "Sat") {
            $noaccess = "yes";
} else {
         $noaccess = "no";
}

Here is the code for displaying the form:

if ($noaccess == "yes") {
echo "You cannot access this area now";
} else {
//Form displays normally 
}
