The Task

Read the users from the xml, csv and json files within the data directory
Merge all users into a single list and sort them by their userId in ascending order
Write the ordered results to new xml, csv and json files, see the examples directory
- Results should use the same structure as the source files they were parsed from
- The exception is for lastLoginTime where an ISO 8601 date format is preferred for output

Requirements

PHP >= 5.3.23 or Any other
composer
Any other OO language

Installation

composer install

Notes

You can also choose continue the provided solution or start fresh.

A sample implementation is provided for parsing and writing xml files, it can be used like this:

<?php

use Pay4Later\PDT\Serializer\Adapter\ClassOptions;
use Pay4Later\PDT\Serializer\Adapter\XmlClass;

require_once __DIR__ . '/vendor/autoload.php';

$config = require __DIR__ . '/config.php';

$xmlSerializer = new XmlClass(
    array(
        ClassOptions::OPTION_CONFIG => $config,
        ClassOptions::OPTION_CLASS  => 'Pay4Later\PDT\User'
    ));

# parse the xml file into an array of Pay4Later\PDT\User
$users = $xmlSerializer->unserialize(file_get_contents(__DIR__ . '/data/users.xml'));

# produce an xml file from an array of Pay4Later\PDT\User
$xmlString = $xmlSerializer->serialize($users);

You are free to implement your solution however you feel most appropriate and will be assessed on the architecture of your solution. We recommend producing a simple, extensible solution and do not require you to complete all the tasks within the allotted time. However, please comment on any assumptions made or design decisions you would have made if you would have done something differently given more time.

Submitting your solution

Please don't fork the repo, as your solution will be public.

Either:

Zip up your solution, omitting the vendor folder
After committing your changes, create a git bundle from your local repo with:

git bundle create solution.bundle master

Submit your solution via email

Solution Rationale

Following a brief investigation of the existing code, the complexity and the amount of time that it would take to cover the existing codebase in tests would be vastly greater than building a new solution.
