如何在每次调用函数时更新laravel控制器中变量的值

class YourController extends Controller
{
    private $yourVariable = 'initial value';

    // ...
}

class YourController extends Controller
{
    private $yourVariable = 'initial value';

    public function updateVariable($newValue)
    {
        $this->yourVariable = $newValue;
    }

    // ...
}

class YourController extends Controller
{
    private $yourVariable = 'initial value';

    public function updateVariable($newValue)
    {
        $this->yourVariable = $newValue;
    }

    public function yourFunction()
    {
        // 调用updateVariable方法更新变量的值
        $this->updateVariable('new value');

        // 可以在此处使用更新后的变量值
        echo $this->yourVariable;
    }
}
