Run PHP: Command Line, Web Server & IDEs

There are multiple ways to run a PHP program, with the most common being:

1. To run a PHP program, simply type “php filename.php” in the command line.
2. To run a PHP program through a web server, place the PHP program in the root directory of the web server (such as Apache’s htdocs directory), and then enter the corresponding URL in a browser to access and run the PHP program.
3. Utilize integrated development environments (IDEs): Using integrated development environments like XAMPP, WampServer, MAMP, etc., can easily run PHP programs locally and provide debugging and monitoring features.
4. There are also online PHP interpreters available, which allow you to input your code directly on a webpage and run it, such as phpfiddle.org.
