🚀 How to Install PHP (Platform-Wise)

🪟 1. Installing PHP on Windows

✅ Method 1: Using XAMPP (Recommended for Beginners)

XAMPP is an all-in-one installer that includes Apache, MySQL, PHP, and phpMyAdmin.

Steps:

1. Download XAMPP from apachefriends.org
2. Run the installer and follow the wizard
3. Launch the XAMPP Control Panel
4. Start Apache and MySQL modules
5. Place your PHP files inside C:\xampp\htdocs
6. Visit http://localhost/filename.php to run your PHP file

✅ Method 2: Manual PHP Setup

For advanced users wanting more control:

1. Download PHP binaries from windows.php.net
2. Extract to C:\php
3. Add C:\php to your system’s Environment Variables
4. Configure php.ini file (copy from php.ini-development)
5. Install and configure Apache or Nginx to process .php files

🐧 2. Installing PHP on Linux

Use your distribution’s package manager:

✅ For Ubuntu/Debian:

sudo apt update
sudo apt install apache2 php libapache2-mod-php

✅ For CentOS/Fedora:

sudo dnf install php php-cli php-common httpd

After installation:

• Place files in /var/www/html/
• Restart Apache:

sudo systemctl restart apache2   # or `httpd` on CentOS

• Open http://localhost to test

🍏 3. Installing PHP on macOS

✅ Option 1: Using Homebrew

brew install php
php -v

✅ Option 2: Use MAMP (Mac version of XAMPP)

1. Download from mamp.info
2. Install and start servers
3. Use htdocs folder for PHP files
4. Access via http://localhost:8888/

🧪 Verifying the PHP Installation

Create a file named info.php:

<?php
phpinfo();
?>

Save it in your server’s document root (e.g., htdocs or /var/www/html) and open it in the browser:

http://localhost/info.php

You should see a detailed PHP configuration page with version info and loaded extensions.

display_errors = On
error_reporting = E_ALL

• Enable useful extensions:

extension=mysqli
extension=openssl
extension=curl

❓ Frequently Asked Questions (FAQs)

❓ Can I install PHP without a web server like Apache or Nginx?
✅ Yes, for CLI scripting only. For web pages, a server is required to interpret .php files.

✅ No. These bundles include MySQL (or MariaDB) and phpMyAdmin.

❓ How do I update PHP to a newer version?
✅ On Windows/macOS, download and replace binaries or update XAMPP. On Linux, use your package manager or third-party repositories (e.g., ondrej/php for Ubuntu).

❓ What’s the best way to install PHP for beginners?
✅ Use XAMPP (Windows/macOS) or MAMP (macOS) — easy, fast, and pre-configured.

❓ Can PHP run in the cloud or Docker?
✅ Yes. PHP is widely used in Docker containers, PaaS platforms like Heroku, and cloud services like AWS.
