The variable $name does not exist. Did you forget to declare it?

The variable $value seems only to be defined at a later point. Did you maybe move this code here without moving the variable definition?

        if ($value[0] === '"' && $value[-1] === '"') {

The variable $value seems only to be defined at a later point. Did you maybe move this code here without moving the variable definition?

            $value = substr($value, 1, -1);

The variable $value seems only to be defined at a later point. Did you maybe move this code here without moving the variable definition?

        }

        return new self($name, $value);

The variable $value does not seem to be defined for all execution paths leading up to this point.
