<?php

/**

?>
<?= $search->field('id')->hiddenInput()->label(false) ?>

    <div class="col-md-2">
        <?= $search->field('graph')->dropDownList(
            array_merge(['' => Yii::t('hipanel:server:rrd', 'Index')],
                array_combine((array) $model->graphs, (array) $model->graphs)),

It seems like array_combine((array)$model->graphs, (array)$model->graphs) can also be of type false; however, parameter $array2 of array_merge() does only seem to accept array|null, maybe add an additional type check?

        ) ?>
