Just make the with the field name and use implode function while inserting data.

For example:

    $data['name'] = 'abc';
    $data['description'] = 'description';
    $data['created'] = date("Y-m-d H:i:s");

Query:

     $fields = array_keys($data);
        $sql = "INSERT INTO table_name . (`" . implode('`,`', $fields) . "`) 
                VALUES('" . implode("','", $data) . "')";
