How to Install PHP: A Step-by-Step Guide

PHP, which stands for “Hypertext Preprocessor,” is a popular server-side scripting language used in web development to create dynamic and interactive websites. Installing PHP on your web server is a fundamental step in building web applications. In this article, we’ll guide you through the process of installing PHP on various platforms.

Before you begin, you’ll need:

  • A web server software (e.g., Apache, Nginx).
  • A working web server setup.
  • Basic command-line knowledge (for some installation methods).
  • Installing PHP on Different Platforms
  • Installing PHP on Windows

If you’re using Windows, one of the easiest ways to get PHP up and running is by using XAMPP or WampServer.

Here’s a simple guide to using XAMPP:

  1. Download XAMPP from the official website (
  2. Run the installer and follow the on-screen instructions.
  3. Choose the components you want to install, including PHP.
  4. After installation, start the Apache server.
  5. Create or place your PHP files in the ‘htdocs’ folder within the XAMPP directory (usually ‘C:\xampp\htdocs’).
  6. Access your PHP files through a web browser (e.g., http://localhost/your-file.php).
  7. Installing PHP on Linux (Ubuntu)

On Ubuntu, you can use the command line to install PHP:

  1. Open the terminal.
  2. Update the package list: sudo apt update
  3. Install PHP along with common extensions: sudo apt install php
  4. Verify the installation: php -v
  5. Your PHP installation on Ubuntu is now complete.

Installing PHP on macOS

On macOS, PHP is pre-installed. However, you can use Homebrew to manage and update your PHP version:

  1. Install Homebrew (if not already installed) by following the instructions at
  2. Install PHP: brew install php
  3. Verify the installation: php -v
  4. You can now use the PHP version installed via Homebrew.

Configuring PHP

After installing PHP, you may need to configure it to meet your application’s specific requirements. The configuration file, php.ini, controls various settings. You can locate it by running php –ini. Common settings to consider include memory limits, error reporting, and file upload size.

For web server integration (e.g., Apache), you may need to configure the server to handle PHP files. This typically involves adding directives like AddType and LoadModule to your server’s configuration.


Installing PHP is an essential step for web developers, enabling the development of dynamic and interactive websites. The process varies depending on your operating system, but with the right tools and a clear guide, it can be a straightforward task. Once PHP is installed, you can start building web applications and websites that leverage the power of this versatile scripting language. Remember to stay updated with security patches and best practices to ensure the security and reliability of your PHP-powered applications.
