Laravel 获取设置要在另一个函数中使用的全局变量

我的主要想法是通过会话传递数据，并通过控制器获取或设置数据，以便在模型中使用

这是我的控制器

$aFilters = $request->all();

if(empty($aFilters)) {

    $aRegions = $this->oChartManager->getRegions();
    $aFilterRegion = [];
    foreach ($aRegions as $aRegion) {
        array_push($aFilterRegion, $aRegion['region']);
    }
    $aFilters['region'] = $aFilterRegion;

}

$request->session()->put('filtered', $aFilters);

$request->session()->put('filtered', $this->oChartManager->addGlobalFilters('region', $aFilters['region']));

$request->session()->put('filtered', $this->oChartManager->getGlobalFilters());

protected $aGlobalFilters = [];

public function addGlobalFilters($sKey, $mValue) {

    $this->aGlobalFilters[$sKey] = $mValue;
}

public function getGlobalFilters() {

    return $this->aGlobalFilters;
}

public function Info() {

     dd($this->aGlobalFilters ); // This get [] 
}

这是我的型号

$aFilters = $request->all();

if(empty($aFilters)) {

    $aRegions = $this->oChartManager->getRegions();
    $aFilterRegion = [];
    foreach ($aRegions as $aRegion) {
        array_push($aFilterRegion, $aRegion['region']);
    }
    $aFilters['region'] = $aFilterRegion;

}

$request->session()->put('filtered', $aFilters);

$request->session()->put('filtered', $this->oChartManager->addGlobalFilters('region', $aFilters['region']));

$request->session()->put('filtered', $this->oChartManager->getGlobalFilters());

protected $aGlobalFilters = [];

public function addGlobalFilters($sKey, $mValue) {

    $this->aGlobalFilters[$sKey] = $mValue;
}

public function getGlobalFilters() {

    return $this->aGlobalFilters;
}

public function Info() {

     dd($this->aGlobalFilters ); // This get [] 
}

问题是我试图从控制器获取数据以用于另一个函数，但即使我在

getGlobalFilters（）

函数中返回，数据也没有传递到函数信息

写

$this->x

而不是

$this->$x

class TestController extends Controller
{
    private $x;

    public function index()
    {
        $this->x ='22';
    }

    public function send_message()
    {
        echo $this->x;
    }
}

比如说

写

$this->x

而不是

$this->$x

class TestController extends Controller
{
    private $x;

    public function index()
    {
        $this->x ='22';
    }

    public function send_message()
    {
        echo $this->x;
    }
}
