Server-side scripting is the practice of writing scripts, in languages like PHP, to dynamically generate pages, update files, process registrations, or other web site functions.
Server-side scripting, as the name implies, runs on the server. This allows the web site developer to develop scripts that will execute before the content is delivered to your site visitor. Since the script is run on our hosting server, clients using any browser or operating system always get the same content and experience.
