PHP is commonly used to build websites with interactive and dynamic features, such as online forums, e-commerce sites, social networks, and content management systems.

This code is executed on the server, which means that the code is processed on the server before the resulting webpage is sent to the user's web browser. This allows developers to create dynamic content that can be customized based on user input or database information.
PHP has a large and active community of developers who create and maintain various libraries, frameworks, and tools that make PHP development faster and more efficient. Some of the popular PHP frameworks include Laravel, CodeIgniter, and Symfony.

Its open-source nature, compatibility with different platforms, and large developer community make it a popular choice for web development.
