PHP, or also known as Hypertext Preprocessor, is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. PHP can be used for a lot of different things, and is one of the most powerful scripting languages available on the web. However, one thing that PHP is lacking, and in fact most scripting languages are, is a way to update pages in real-time, without having to reload a page or submit a form. If you're building a PHP application (e.g. a high-quality content management system), then it'd be ideal if it worked almost like a native Windows/Linux application. If you want to execute a PHP script, you need to reload a page, submit a form, or something similar. Basically, a new connection to the server needs to be opened, and this means that the browser goes to a new page, losing the previous page.
