Is it possible to read a csv file column by column with League csv?

Question

I wondered if it was possible to read a csv file written like this in symfony using League csv or something else.

      water_level,2,456,345
      wind_speed,25,456,56
      food_level,10.4,123,23
      animal_count,56,34,124
      number_of_machines,150,345,54
      machineId,1234567,1234568,1234567

Header in the first column and data in the next columns.

Right now, I can read the files when the header is in the first row, I just want to know if it's possible to read it the other way!

I tried transposing but I get an error. I don't really know what's causing it if the array really is transposed.

    $pathString = implode($newFilesPath);
    $reader = (Reader::createFromPath($pathString))->setHeaderOffset(0);
    $results = $this->transpose(iterator_to_array($reader->getRecords()));

    foreach ($results as $row) {

        $properties = (new AppProperty)
            ->setWaterLevel($row['water_level'])
            ->setWindSpeed($row['wind_speed'])
            ->setFoodLevel($row['food_level'])
            ->setAnimalCount($row['animal_count'])
            ->setNumberOfMachines($row['number_of_machines'])
            ->setMachineId($row['machineId'])
            ->setDate(new \DateTime());

            $this->em->persist($properties);
    }

    $this->em->flush();
 }

private function transpose ($array){
    return array_map(null, $array);
}

The error:

Argument 1 passed to App\Entity\Property::setWaterLevel() must be of the type int or null, string given.
It looks like the transpose just didn't work.
