If a new column is added to the data, you have to update all the indexes where that array is used. The method of using associative arrays is far better than an indexed array, as it can often be confusing, cause errors trying to remember what piece of data is at any given numerical index, and code maintenance is often a minefield. To get the associative array, the first row of data is used as the column headings, then a loop runs over each item in the array from fgetcsv and inserts it against the column heading. In particular, you're wanting to sort from highest to lowest, based on price. For this example, let's say you're trying to sort a.
