PADUA - CSV file upload

---

Approach

• I decided on using Laravel 8 for this due to the framework making it easier to structure the code base.
• I have split the functions used to verify to the transaction codes into a helper class, as if this was a production project then those functions will probably be used elsewhere.
• I used the str_getcsv method to read each row, then column, of the csv data. This was done to prevent needing to write any files to the disc.
• The project uses a single blade template to display the button to upload the file, and display the table. This prevents code duplication.
