Yii2-如何在我的GridView中格式化页脚？

这是我的GridView的代码。我希望页脚与其列的格式相同。我该怎么做？谢谢

echo GridView::widget([
'dataProvider' => $dataProvider,
'showFooter' => true,
'formatter' => ['class' => 'yii\i18n\Formatter','thousandSeparator' => ',','currencyCode' => 'PHP',],
        'columns' => [
        ['class' => 'yii\grid\SerialColumn'],

        [
        'attribute' =>'account_code',
        'footer' =>'Total',
        ],
        'account_name',
        [
        'attribute' =>'amount',
        'format' => 'currency',
        'footer' => Accounts::getTotal($dataProvider->models, 'amount'),
        ],

        ['class' => 'yii\grid\ActionColumn'],
        ],

]))

只需添加前缀

 'footer' => 'PHP' . Accounts::getTotal($dataProvider->models, 'amount'),

对于千位分隔符，可以使用数字\格式

'footer' => 'PHP' .
       number_format (Accounts::getTotal($dataProvider->models, 'amount'), 2 , "." ,  "," )

只需添加前缀

 'footer' => 'PHP' . Accounts::getTotal($dataProvider->models, 'amount'),

对于千位分隔符，可以使用数字\格式

'footer' => 'PHP' .
       number_format (Accounts::getTotal($dataProvider->models, 'amount'), 2 , "." ,  "," )
