PHP stands for PHP: Hypertext Preprocessor and is a server side scripting language specialized in describing web pages. In short, it is a programming language that is useful for creating bulletin boards and chats that run on the web. There are two kinds of scripts, client side script and server side script. A client side script is a script that processes on a client side WEB browser like JavaScript. The result of script execution may be unintended by the user, depending on the type of browser used by users such as InternetExplorer and Netscape, and the environment setting. Server side script is a script that WEB server performs processing. The server that received the request returns the processing result to the client side. In addition to PHP, there are JSP, ASP / ASP.NET and others.
