PHP, the popular scripting language, is widely recognized for its prowess in web development. However, it offers more than just website creation. With PHP CLI (Command Line Interface), you can harness the power of PHP scripts without the need for a browser. In this comprehensive guide, we will delve into the world of PHP CLI, exploring its benefits, use cases, and how to execute PHP scripts right from your command line interface.

What is PHP CLI?

PHP CLI stands for PHP Command Line Interface. It allows developers to execute PHP scripts directly through a command line terminal, bypassing the need for a web browser. This feature-rich interface opens up a multitude of possibilities beyond traditional web development, enabling tasks like scripting, automation, and data processing.

How to Execute PHP Scripts from the Command Line

Executing PHP scripts from the command line is remarkably straightforward. Follow these steps to unlock the potential of PHP CLI:

1. Open a Command Line Terminal: Launch your preferred command line terminal on your computer. On Windows, you can use Command Prompt or PowerShell, while Unix-based systems like Linux and macOS use the Terminal.
2. Navigate to PHP Installation Directory: If PHP is not in your system’s PATH, navigate to its installation directory using the ‘cd’ command.
3. Write Your PHP Script: Use a text editor to create your PHP script. Save it with the ‘.php’ extension. For example, create a file named ‘myscript.php’.
4. Run the PHP Script: In the command line terminal, navigate to the directory containing your PHP script using the ‘cd’ command. Then, execute the script using the command php myscript.php.
5. View Output: Once executed, the script’s output will be displayed directly in the terminal.
