Structural representation of CSV

Structural representation of CSV Time: Maximum 2h (timebox) + report Deliverables: Report (0.5 ‒1 page) + code Background Comma-separated value (CSV) files are a common office format which is popular for export and import of data when working with Excel. Representing CSV files in a manageable way is a common problem in data management and would benefit from a generic solution. Assignment In order to efficiently import and export CSV files we would require a generic class structure that can handle arbitrary CSV formats. The class should be able to load a CSV file either as string content or as a file resource. 1. Example implementation of file using the class is provided. 2. Only one-dimensional arrays are permitted, additional complexities in the structure should be implemented as objects. 3. Regular expressions are not permitted since parsing a CSV file can be done easily without it. 4. Focus should be on readable, maintainable code. Bonus point for good structure and design patterns. 5. If possible the class should be storable in Doctrine. The assignment is limited to two hours as per timeboxing principles which include research but not reporting. Result should be presented in a report which shall include any conclusions as well as a proposal for an implementation (in whole or part). Links 1. Iterator (h ttp://[login to view URL]) 2.
