When using PHP intelephense in VS Code for my laminas project, it is showing error,

Undefined method 'toArray'

My code looks as below,

<?php

namespace SomethingModel;

use LaminasDbAdapterAdapter;
use LaminasDbSqlSelect;

use InfrastructureAbstractionAbstractTableGateway;

class SomethingModel extends AbstractTableGateway
{
    protected $table = 'some_table';

    public function __construct(Adapter $adapter)
    {
        $this->adapter = $adapter;
    }

    public function getSomething($arrTraitId)
    {
        return $this->select(function (Select $select) use () {
            $select->columns(['something']);
        })->toArray();
    }
}

I was able eliminate this error by changing the code as follows,

        /** @var LaminasDbResultSetAbstractResultSet $select **/
        $select = $this->select(function (Select $select) use ($arrTraitId) {
            $select->columns(['spirit_trial_id']);
            $select->where(['spirit_trial_id' => $arrTraitId]);
        });
        return $select->toArray();

But i don’t want it to assign to any variable. So is there any alternative way to remove the error?
