Build a Supplier Product List Processor

Requirement:

We have multiple different formats of files that need to be parsed and returned back as a Product object with all the headings as mapped properties.

Each product object constitutes a single row within the csv file.

Example Application API:

parser.php --file example_1.csv --unique-combinations=combination_count.csv

When the above is run the parser should display row by row each product object representation of the row. And create a file with a grouped count for each unique combination i.e. make, model, colour, capacity, network, grade, condition.

Example Product Object:

• make: 'Apple' (string, required) - Brand name
• model: 'iPhone 6s Plus' (string, required) - Model name
• colour: 'Red' (string) - Colour name
• capacity: '256GB' (string) - GB Spec name
• network: 'Unlocked' (string) - Network name
• grade: 'Grade A' (string) - Grade Name
• condition: 'Working' (string) - Condition name

Example Unique Combinations File:

• make: 'Apple'
• model: 'iPhone 6s Plus'
• colour: 'Red'
• capacity: '256GB'
• network: 'Unlocked'
• grade: 'Grade A'
• condition: 'Working'
• count: 129

Things to note:

• New formats could be introduced in the future ie. (json, xml etc).
• File headings could change in the future.
• Some files can be very large so watch out for memory usage.
• The code should be excutable from a terminal.
• Please provide brief read me describing how to run your application.
• PHP 7+ must be used.
• Should be built using native PHP and no third party libraries.
• Required fields if not found within file should throw an exception.

Bonus:

• Add unit/integration tests.

Example files can be found in the examples directory.
