One way to get copies of these files is to right…click the link of each one and then save link as.…But since we're using PHP, let's create a script to do it for us.…The first thing that we need is the URL.…So if we can copy from the address from…the browser, and then go to our editing program.…And we need to create a new PHP file.…And save that as get_full_years.php.…
By default, PHP scripts automatically terminate after 30 seconds.…So unless you've got a really fast internet…connected, that's too short to download all the files.…So we need to remove the time limit, we can…
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.
