You're talking about one single controller, right? So I'll assume that this what you mean:
你说的是一个控制器，对吧？所以我假设这就是你的意思：
class ControllerController extends Controller {
private $variable;
public function __construct($whatever)
{
$this->variable = $whatever;
}
public function method1($newValue)
{
$this->variable = $newValue;
}
public function method2()
{
return $this->variable;
}
}
If you are doing thing in the same request, you can
如果你在同一个请求中做事情，你可以
$this->method1('newvalue');
echo $this->method2();
And it will print newvalue.
它会打印newvalue.
If you are doing it between requests, you need to remember that your application ends after a request a restart in a new one, so you'll need to store it somewhere, like in a Session variable:
如果您在请求之间执行此操作，您需要记住您的应用程序在请求重新启动后结束，因此您需要将其存储在某处，例如在 Session 变量中：
Session::put('variable', $newvalue);
and then
进而
Session::get('variable');
Or you can redirect with the value you need to get back in your method:
或者，您可以使用返回方法所需的值进行重定向：
Redirect::to('posts')->with('variable','this is a new value');
And in the second
而在第二
Session::get('variable');
