Question

我有一个具有功能的控制器，我想通过它们使用一个变量

  public function one(){
    $variable = "some data";
  }

  public function two()
  {
    //How to use $variable here ?!
  }

让它成为一个属性

class TrainerController extends \BaseController 
{

  private $variable;

  public functionOne(){
    $this->variable = "some data";
  }

  public functionTwo()
  {
    echo $this->variable; //outputs 'some data' IF this 1st method has already been called
  }
}
