What is a php program?

A PHP program is a script written in the PHP programming language, which is commonly used for web development. PHP is a server-side scripting language, meaning that the code is executed on the server rather than on the client's browser.

PHP programs can be used to create dynamic web pages, process form data, interact with databases, and perform various other tasks on the server. PHP is often integrated with HTML and CSS to create a complete web application.

PHP programs are typically stored in .php files and can be run on a server that has PHP installed. The code is processed by the server and the output is sent to the client's browser.

PHP is a versatile language that is widely used in web development, and there are many frameworks and libraries available to help developers create robust and secure applications.
