By default PDO uses the PDO::FETCH_BOTH as its fetch result. Meaning that it maps every column to its name and to an 'integer' column name.

Check the fetch_style param= http://php.net/manual/en/pdostatement.fetch.php

For your expected result you will need to use the PDO::FETCH_ASSOC attribute. You can or set this as the default FETCH_MODE on the pdo object as follows:

$this->db->setAttribute(\PDO::ATTR_DEFAULT_FETCH_MODE, \PDO::FETCH_ASSOC);

Or you can specify it for every fetch cal:

$value = $statement->fetchAll(PDO::FETCH_ASSOC);
