PHP

PHP stands for "Hypertext Preprocessor". PHP is a server-side scripting language that integrates with HTML to create dynamic web pages. so php is a scripting language that is attached to the HTML that is server-side.

server-side scripting is the syntax and commands given will be completely executed on the server but is included in an HTML document. so the server will run and process the PHP file and the browser will display a HTML file. so users will not be able to see the PHP program code and the security of a web page to be more secure

advantages and capabilities of PHP.

  1. Open Source (Free).
  2. With multiple OS support.
  3. Can send the HTTP header.
  4. May set cookies.

need to know! 
Server-side scripting is a web server technology in which a user's request is verified by running a script directly on the web server to generate dynamic web pages. It is usually used to provide interactive web sites that interface to databases or other data stores. This is different from client-side scripting where scripts are run by the viewing web browser, usually in JavaScript. The primary advantage to server-side scripting is the ability to highly customize the response based on the user's requirements, access rights, or queries into data stores.

From a security point of view, server-side scripts are never visible to the browser as these scripts are executed on the server and emit HTML corresponding to user's input to the page.

When the server serves data in a commonly used manner, for example according to the HTTP or FTP protocols, users may have their choice of a number of client programs (most modern web browsers can request and receive data using both of those protocols). In the case of more specialized applications, programmers may write their own server, client, and communications protocol, that can only be used with one another.

Programs that run on a user's local computer without ever sending or receiving data over a network are not considered clients, and so the operations of such programs would not be considered client-side operations..
