推薦答案
您說的是單個控制器，對嗎?所以我假設這就是你的意思:
You're talking about one single controller, right? So I'll assume that this what you mean:
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;
}
}
如果你在同一個請求中做事情，你可以
If you are doing thing in the same request, you can
$this->method1('newvalue');
echo $this->method2();
它會打印newvalue.
如果您在請求之間執行此操作，您需要記住您的應用程序在請求重新啟動后結束，因此您需要將其存儲在某處，例如在 Session 變量中:
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:
Session::put('variable', $newvalue);
然后
Session::get('variable');
或者您可以使用返回方法所需的值進行重定向:
Or you can redirect with the value you need to get back in your method:
Redirect::to('posts')->with('variable','this is a new value');
然后在第二個
Session::get('variable');
