Join David Powers for an in-depth discussion in this video Creating an associative array from a CSV file, part of Code Clinic: PHP.

- A problem with the Table From CSV function…that we created earlier,…is that it gives you no control…over how the CSV data is formatted,…nor can you change the order of the data.…To overcome these limitations,…let's create a function that extracts data…from a CSV file and converts it…into a multidimensional associative array…similar to the result from a database query.…So in csv_functions.php scroll down to the bottom,…and that's where we'll define the function,…and we'll call it extractCsv.…
It will take two arguments.…The first one will be ($filename,…and the second will be a Boolean value…indicating whether the first line of the CSV file…contains column titles.…So we call that $titles, and we set its default value…to true so it becomes optional.…In fact, these are exactly the same arguments…as used by Table From CSV.…We can even borrow some code from that function.…Scroll up to the top and copy from Line 3…down to Line 10,…and then paste that inside the new function.…
And we need to do a little bit of adjustment here…
David introduces challenges and provides an overview of his solutions in PHP. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
