What are the differences between using "sort=price" and "sort=-price" in PHP when sorting Amazon API articles by price?

When sorting Amazon API articles by price, using "sort=price" will sort the articles in ascending order based on price, while using "sort=-price" will sort the articles in descending order based on price. This means that "sort=price" will display the cheapest articles first, while "sort=-price" will display the most expensive articles first. 

// Sorting Amazon API articles by price in ascending order
$sort = "price"; // cheapest articles first

// Sorting Amazon API articles by price in descending order
$sort = "-price"; // most expensive articles first
