Why Do You Need to Install PHP?

Before you can run PHP scripts, you need to install PHP on your system. PHP is a server-side language, and it requires a web server (like Apache or Nginx) and an interpreter to process PHP files.

PHP Can Be Installed in 3 Ways:

Standalone (just PHP)
With a local server stack (like XAMPP, WAMP, MAMP, LAMP)
In a virtual environment or container (Docker)

Prerequisites for PHP Installation

Basic knowledge of your operating system (Windows/macOS/Linux)
Administrative privileges to install software
An internet connection to download PHP and required packages

Installing PHP on Windows (Beginner Friendly)

There are two popular ways to install PHP on Windows:

Method 1: Using XAMPP (Recommended for Beginners)

XAMPP is an easy-to-use Apache distribution that includes PHP, MySQL, and phpMyAdmin.

Steps:

Go to apachefriends.org
Download the latest XAMPP version for Windows
Run the installer and follow the wizard
Start Apache and MySQL from XAMPP Control Panel
Place your PHP files in the htdocs folder
Open your browser and visit http://localhost/yourfile.php

Method 2: Manual Installation

Steps:

Download PHP from php.net
Extract the ZIP file to C:\php
Add C:\php to your system PATH
Verify installation with:

php -v

Configure php.ini

Use Setting Up PHP Environment to complete your manual setup.

Installing PHP on macOS

macOS comes with PHP pre-installed (in older versions), but it’s often outdated. You can install the latest version via Homebrew.

Steps:

Install Homebrew if not installed:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install PHP:

brew install php

Verify installation:

php -v

Start PHP’s built-in server (for development):

php -S localhost:8000

MAMP for Beginners

MAMP is a macOS-friendly server stack similar to XAMPP.

Download from mamp.info
Drag and drop to Applications
Place files in htdocs
Access via localhost

Installing PHP on Linux (Ubuntu/Debian-Based Systems)

Installing PHP on Linux is straightforward using package managers.

Steps:

Update your system:

sudo apt update

Install PHP and required modules:

sudo apt install php libapache2-mod-php php-mysql

Verify:

php -v

Restart Apache:

sudo systemctl restart apache2

For Fedora/CentOS-based systems, use dnf or yum package manager.

Using PHP’s Built-in Web Server

PHP offers a built-in server ideal for testing and development.

How to Use:

cd /path/to/project
php -S localhost:8000

Then visit http://localhost:8000 in your browser.

Installing PHP with Docker (Advanced)

For scalable environments, Docker is a modern solution.

Example Dockerfile:

FROM php:8.2-apache
COPY . /var/www/html/
EXPOSE 80

Use with Docker Compose or pull prebuilt images:

docker run -d -p 8080:80 php:8.2-apache

Testing Your PHP Installation

Create a simple test file:

<?php
phpinfo();
?>

Save it as info.php and run it from your browser to confirm PHP is working.

Troubleshooting Common PHP Installation Issues

Port 80 is busy: Change to port 8080
PHP not recognized: Add it to PATH
php.ini missing: Copy php.ini-development as php.ini
Permission errors: Run commands with sudo

Best Practices for PHP Setup

Use the latest stable version of PHP
Keep php.ini configurations optimized
Regularly update your stack (XAMPP, WAMP, etc.)
Never expose your development server to the public

What to Do After PHP Installation

Learn the Syntax Overview of PHP
Start creating scripts and explore file handling
Set up databases with MySQL or MariaDB
Work on small projects to build confidence
