Join David Powers for an in-depth discussion in this video Getting data from a CSV file: The basics, part of Code Clinic: PHP.
- Let's begin by looking at the basic php code…to extract data from a csv file.…If you want to follow along with me…copy the _assets folder from the exercise files…for this video to your testing site.…It contains two files, first_semester.csv…and second_semester.csv.…We need to create a php file to work with.…So I'm gonna save that as getcsv.php…and the first thing to do is to open the csv file.…
We'll use the fopen function…which returns a fire handle,…in other words a reference to the file.…So we'll save that as file and fopen…and the file that we want to open is in _assets…and it's the first_semester.csv.…The second argument is the mode that we want to open it in.…We want to read it, so the mode is r as a string.…With the file open in read mode…we can get the data one line at a time…using the fgetcsv function…which passes the csv data into an array.…
The basic structure looks like this.…Data that will be our array from one line…and then fgetcsv and we pass it the reference to the file.…We need to run this in a while loop…
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.
