Question

Please what is the best way to get the new value of a variable after the exit function in php. My script below is a sample, I want to get new value of variable $ee and use it to echo an error message after calling exit function.

$ee = 0;
$required = array('name', 'location', 'email', 'school', 'age');

if(isset($_POST['name'])){

    foreach($required as $ff){
    if(empty($_POST[$ff])){
    header("location:register.php");
    $ee = 1;
    exit($ee);          
    }
    }

    }

The easiest way to keep that variable alive is through PHP $_GET, example:

foreach($required as $ff){
    if(empty($_POST[$ff])){
        $ee = 1;
        $encoded_ee = urlencode($ee);
        header("location:register.php?error=" . $encoded_ee);
        exit($ee);          
    }
}
