I have tried your CSVReader function. It gives me perfect result as per my need. I also like your idea to check if the CSV fields/headers match to one of your database table fields to insert the row. It gives result array as below.

Array
(
    [0] => Array
        (
            [Years] => 1888
            [Make1] => Acura
            [Make2] => Honda
            [Make] => Honda
            [] => Honda
            [Makes] => Toyota
)

I have also tried CSVReader library at this location. https://github.com/bcit-ci/CodeIgniter/wiki/CSVReader But it gives result array with values imploded by comma(,) as below.

Array
(
    [0] => Array
        (
            [Years,Make1,Make2,Make,,Makes,Make] => 1888,Acura,Honda,Toyota,Honda,Toyota,Honda
        )
)

Now SubRed, in your CSVReader function, I have made changes to CSV file's first row name with whitespace at the end. But after that in the CI controller, while I am checking that fields/headers/column_name exists in CSV file with array_key_exists('column_name',$csvdata), it returns false/none because of whitespace in the column_name field at the end. So I have updated your code.

Please refer below updated code and give me any suggestions if any.

EDIT :- Make changes to the foreach loop in parse_lines function in CSVReader file =>

foreach( $this->fields as $id => $field ) {  
    //echo $id;
    //echo $field;
    //In CSV File, trim(remove both end whitespaces) the first line which contains fields names
    $field = trim($field);
    if( isset($elements[$id]) ) 
    {
        $item[trim($field)] = trim($elements[$id]);//In CSV File, trim all the file data
    }
 }
