yii2如何显示更高的值

Question

如何显示更高的值，例如，如果mass > volume则mass price出现在gridview中，如果mass < volume则volume price出现。我这样用源码还是不行

    [
        'label' => 'Tarif',
        'format' => 'Currency',
        'value' => function ($model) {
            if ($volume= $model['rate'] * Yii::$app->request->get('TarifCargoSearch')['panjang'] * Yii::$app->request->get('TarifCargoSearch')['lebar'] * Yii::$app->request->get('TarifCargoSearch')['tinggi'] / 4000)
                return $volume;
            else if ($mass= $model['rate'] * Yii::$app->request->get('TarifCargoSearch')['massa'])
                return $mass;
            else if ($volume > $mass)
                return $volume;
            else if ($volume < $mass)
                return $mass;
        }
    ],

[
    'label' => 'Tarif',
    'format' => 'Currency',
    'value' => function ($model) {
        $volume = $model['rate'] * Yii::$app->request->get('TarifCargoSearch')['panjang'] * Yii::$app->request->get('TarifCargoSearch')['lebar'] * Yii::$app->request->get('TarifCargoSearch')['tinggi'] / 4000;
        $mass = $model['rate'] * Yii::$app->request->get('TarifCargoSearch')['massa'];

        return $mass > $volume? $mass : $volume;
    }
],

检查一下并告诉我，请确保您的计算正确。

[
    'label' => 'Tarif',
    'format' => 'Currency',
    'value' => function ($model) {
        // Please note that the $model will be object not an array
        $volume = $model->rate * Yii::$app->request->get('TarifCargoSearch')['panjang'] * Yii::$app->request->get('TarifCargoSearch')['lebar'] * Yii::$app->request->get('TarifCargoSearch')['tinggi'] / 4000;
        $mass = $model->rate * Yii::$app->request->get('TarifCargoSearch')['massa'];

        return $mass > $volume? $mass : $volume;
    }
],
