PHP, a popular server-side scripting language, is widely used for web development and powers numerous websites and applications. As a tech advisor, I assure you that PHP is not only beginner-friendly but also a powerful programming language to tech start your coding journey, Let me walk you through the process of installing PHP on your Ubuntu system. We will cover the installation steps, basic configuration, testing the installation, and executing a simple addition code using PHP’s command-line interface (CLI). Additionally, we’ll explore how PHP is utilized in the tech industry. Let’s get started!

Step 1: Installing PHP:

To install PHP on your Ubuntu system, open the terminal and enter the following command:

sudo apt update
sudo apt install php

The package manager will download and install PHP along with the necessary dependencies.

Create a new file, for example, addition.php, using a text editor of your choice. Add the following code to perform a simple addition:

<?php
$number1 = 10;
$number2 = 5;
$sum = $number1 + $number2;
echo "The sum of $number1 and $number2 is: $sum";
?>

Save the file and open a terminal. Navigate to the directory where the addition.php file is located and execute the following command:

php addition.php

The output will display the sum of the two numbers.

Usage of PHP in the Tech Industry:

PHP is widely adopted in the tech industry and powers numerous websites and applications. Prominent companies such as Facebook, Wikipedia, WordPress, Slack, and Etsy rely on PHP for their core systems and web development needs. Its versatility, vast community support, and extensive frameworks like Laravel and Symfony make PHP a go-to choice for developers worldwide.
