How can developers create a test development environment for PHP programs without using additional software?

Developers can create a test development environment for PHP programs by utilizing the built-in PHP web server. This allows them to run and test PHP scripts locally without the need for additional software installations. By simply running a command in the terminal, developers can start the PHP web server and access their PHP files through a local URL.

// Open a terminal and navigate to the directory containing your PHP files
// Run the following command to start the PHP web server
// php -S localhost:8000
// Access your PHP files through http://localhost:8000
