Updating Drupal core can be a difficult process because Drupal still doesn't support core update in online way. We must download the core first, extract it, then upload it to our server manually. This process can take more time because of so many manual operations. In order to solve that problem, I try to create a PHP script to make the update process easier. We just need to open a URL with some query string and then the script will download the requested Drupal core to our server. What we need to do next is run the update.php.

If you have a long running PHP script that executes many processes, you may need to inform user about the progress of the process when the script is still running and hasn't finished yet. Using progress bar can be the best option. We can combine the PHP flush() function, Javascript, and also CSS to create a nice progress bar.

Creating paging in traditional way can be troublesome, especially if you have to create it for many pages. This class will help you to solve that problem. By using this class you can create pagination with PHP and MySQL easily with just a few lines of code.

This is a PHP script that can be used to manage the download process. The advantages of using PHP script for handling the download process is we can prevent user to download the file directly, we can also limit the download speed to the desired speed, and we can also count how many times that file has been downloaded.

The script below has some features such as :

• Configurable download speed.
• Resumable download capability.
