Sales Report: Aggregate a CSV
Read a table of sales rows, group them by region, and surface the top performer. The exact data loop every PHP backend lives in.
What you'll be able to build
Read a table of sales rows, group them by region, and surface the top performer. The exact data loop every PHP backend lives in. Along the way you pick up real, transferable PHP skills, not just this one project:
- parsing rows with explode or str_getcsv
- grouping with associative arrays
- array_sum and arsort
- array_reduce for totals
- ranking and formatting
- tabular output with printf

How the lessons actually work
Every lesson has you predict what a piece of PHP code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Sales Report, and a runnable proof page tied to your own code.
