Running the Application

Run locally, or make commands described below.

This is a PHP 7.4 application. If you have it (and composer) installed locally, then simply run:
composer install
composer test

This Makefile has some options to run the application in docker if you do not have 7.4 locally.
The docker image is webdevops/php-dev:7.4

Usage: make [subcommand]
subcommands:
  ci   Mounts current pwd and run composer install in a docker image
  test Mounts current pwd and run composer test in a docker image
  dev  Mounts current pwd and run composer test (with xDebug 3 enabled) in a docker image

$ make dev args=--testdox

Student Details Application

This task evaluates the candidate's skills in PHP7.

Introduction

The idea of this project is to keep students’ details in a file and fetch them from the file when necessary.

Problem Statement

1. Please do NOT modify any tests unless specifically told to do so.
2. Make tests pass by implementing missing features in the production code. The application is dependency-free.

Task 1

Implement the getData() method in the StudentDetailsImporter class. It should read student records from a given CSV file. Map the records to the Student class and add them to the StudentDetailsImporter->studentList. The first row contains the headers, which means that you need to assign them to StudentDetailsImporter->headers variable. Please note that the order of the students on the list should be the same as in the CSV file.

Task 2

Implement the getSuperStudent() method in the StudentDetailsImporter class. It should return the super student, i.e., the student who has the highest average_score. When looking for such students, the average score is modified according to the following rules:

• add 5 points, if the student is studying computer science,
• add 10 points, if the student is studying maths,
• add 15 points, if the student’s name starts with y (case-sensitive),
• add 20 points, if the student’s id can be divided by two,
• add 25 points, if the student has an A+ grade.

Task 3

Implement the getAttendance() method in the StudentDetailsImporter class. It should read data from a CSV file, specified by the attendance_file_name argument, and use it to calculate the attendance for every student.

The input CSV file has two columns:

• student ID,
• information indicating if the student attended a class:
  • Y means that the student attended a class, so you should increase the Student->attendance attribute.
  • N means that the student did not attend a class, so the Student->attendance attribute stays the same.
