How can the use of classes improve variable handling in PHP scripts?

Using classes in PHP scripts can improve variable handling by encapsulating data and functionality into objects. This helps in organizing code, reducing code duplication, and improving code readability. Classes also allow for better data manipulation and control through the use of access modifiers like public, private, and protected. 

class User {
    private $username;
    
    public function setUsername($username) {
        $this->username = $username;
    }
    
    public function getUsername() {
        return $this->username;
    }
}

$user = new User();
$user->setUsername('JohnDoe');
echo $user->getUsername(); // Output: JohnDoe
