Welcome to your first step into web development! If you have ever wondered how dynamic websites like Facebook or WordPress work behind the scenes, the answer often involves PHP. This tutorial covers PHP Installation and helps you set up everything needed to start coding right away.
This is Tutorial 1 of 10 in our PHP Basics for Beginners series. By the end of this guide, you will have a working local server environment and will have written your very first PHP script.
What is PHP?
PHP stands for Hypertext Preprocessor. It is a server-side scripting language designed specifically for web development. Unlike HTML or CSS, which run in the browser, PHP code runs on the server and sends plain HTML output to the browser. This makes PHP perfect for building dynamic, interactive websites such as blogs, e-commerce stores, and login systems.
PHP powers a huge portion of the internet, including major platforms like WordPress, Facebook (originally), and Wikipedia. Learning PHP Installation correctly is the first practical step before you can write and test any PHP code on your own computer.
Why PHP Installation Matters
Before writing PHP code, your computer needs a server environment that understands PHP. Browsers cannot run PHP directly — only a server can process it. That is why proper PHP Installation is essential. Without it, your .php files will not execute correctly and will simply download as text instead of running as a webpage.
Tools You Need for PHP Installation
There are several tools available for local PHP Installation. The two most popular options for beginners are:
- XAMPP — A free, cross-platform package that includes PHP, MySQL, and Apache server
- Laragon — A modern, lightweight alternative popular among Windows developers
For this series, we recommend XAMPP because it is beginner-friendly, well-documented, and works the same way across Windows, macOS, and Linux.
Step-by-Step PHP Installation with XAMPP
Follow these steps carefully to complete your PHP Installation:
- Visit the official Apache Friends website and download XAMPP for your operating system
- Run the installer and keep the default components selected (Apache, MySQL, PHP, phpMyAdmin)
- Once installed, open the XAMPP Control Panel
- Click “Start” next to Apache — the status should turn green
- Open your browser and go to
http://localhostto confirm the server is running
If you see the XAMPP welcome page in your browser, your PHP Installation is successful and your local server is ready to use.
Writing Your First PHP Script
Now that PHP Installation is complete, let’s write your first script. Navigate to the htdocs folder inside your XAMPP directory. This is where all your PHP project files must be placed.
Create a new file named index.php and add the following code:
<?php
echo "Hello, my PHP Installation is working!";
?>Save the file, then open your browser and visit http://localhost/index.php. You should see the message printed on the screen. Congratulations — you have just executed your first PHP script!
Understanding PHP Tags
Every PHP script must start with <?php and end with ?>. Anything written between these tags is treated as PHP code, while everything outside is treated as regular HTML. This is what allows PHP to be embedded directly inside HTML pages.
For more detailed technical documentation on PHP syntax and installation requirements, you can refer to the official PHP installation manual.
Common PHP Installation Issues
If Apache does not start in XAMPP, it is often because port 80 is already in use by another application like Skype or IIS. Changing the Apache port to 8080 in the XAMPP configuration usually resolves this issue. If PHP files download instead of displaying in the browser, double-check that you placed your file inside the htdocs folder correctly.
What’s Next?
With your PHP Installation complete and your first script running successfully, you are ready to move forward. In the next tutorial, we will explore PHP Variables and Data Types — the building blocks of every PHP program.

Practice Exercise
Complete the following tasks to reinforce what you learned in this tutorial:
- Download and install XAMPP (or Laragon) on your computer
- Start the Apache server and confirm it is running via localhost
- Create a file named
practice.phpinside the htdocs folder - Write a PHP script that echoes your full name
- Write a second echo statement that prints “I completed PHP Installation successfully”
- Open the file in your browser and confirm both messages display correctly
Bonus Challenge: Try changing the Apache port from 80 to 8080 in the XAMPP config, restart Apache, and access your script using the new port number (e.g., http://localhost:8080/practice.php).
