Before we dive into the specifics of the pear PHP_Shell in FreeBSD, let’s briefly cover some basics for beginners in FreeBSD. FreeBSD, like Linux, is open-source software and an efficient operating system for a variety of applications. One of the unique features of FreeBSD are the ports. Essentially, ports are a collection of software or applications that are readily available to install and use in FreeBSD.

Today, we’ll focus on the PEAR PHP_Shell port, which falls under the category of ‘Shells’.

For those who might need some clarification; a shell, in essence, is a command-line interpreter. It provides an interface for users to interact with the operating system. It’s like the medium that facilitates your dialogue with your system.

#### Installation

To install the pear PHP_Shell in FreeBSD, you can use the following command -

# pkg install pear-PHP_Shell

This command will install the pear-PHP_Shell port and any necessary dependencies.

#### Configuration 

Once installed, there aren’t many configurations required for the pear PHP_Shell. You can start it directly from the command line by typing php-shell.

#### Working with the PEAR PHP_Shell

PEAR PHP_Shell is an interactive PHP shell. Once you run php-shell, you can start writing PHP commands right in your terminal, and the results will be outputted on the screen in real time.

>>> echo 'Hello, FreeBSD!';
Hello, FreeBSD!

Handling errors in your PHP code is also a breeze with PEAR. Whenever you insert an incorrect PHP command, it will throw an error, just like the PHP interpreter would in a web server environment.

#### What Does The PHP_Shell Bring To The Table?

When it comes to the benefits of using PEAR PHP_Shell, the biggest one is likely the convenience of testing PHP code directly from the terminal. Here are a few benefits that come with using the PHP_Shell

• It facilitates rapid testing of PHP code snippets without having to create a PHP file and running it on a server.
• It provides real-time feedback.
• It can execute PHP scripts.
• It comes with a set of additional shell commands that extend its functionality.

## Additional Commands

• print Print a string.
• cd Change the current directory.
• ls Lists the directory content.
