How to use if else nested

Below is the original code

else if ($sensor['result_type'] == 'logic')
{
    if($param_value == 1)
    {
        $result['value'] = $param_value;
        $result['value_full'] = $sensor['text_1'];
    }
    else
    {
        $result['value'] = $param_value;
        $result['value_full'] = $sensor['text_0'];
    }
}

else if ($sensor['result_type'] == 'value')
{

I would like to increase the results to 6 text results

so depending on the sensor output it will choose the correct result is sensor result value =0 full result = text_0 and so on till _text_6

I hope this makes sense
