How to Install PHP on Ubuntu Linux: A Step-by-Step Guide

Checking for Existing PHP Installation

• 💡 Before installing, check if PHP is already present on your system by typing php -v in the terminal.
• ⚠️ If PHP is not installed, you'll see an error message, indicating the need for a fresh installation.

Finding Official Installation Instructions

• 🌐 Navigate to the official php.net website and find the 'downloads' section for installation instructions.
• 💻 Select your specific Linux distribution; this guide focuses on Ubuntu.

Preparing for Installation

• ⚙️ It's recommended to run sudo apt update to refresh your package lists before installation, ensuring you get the latest available versions.
• ✅ The command sudo apt install -y php is used to install PHP, with the -y flag automatically confirming all prompts during the process.

Verifying the PHP Installation

• ⏳ Monitor the installation progress in the terminal as packages are downloaded and configured.
• ✅ Once the installation is complete, verify it by running php -v again, which should now display the installed PHP version, such as 8.3.6.
