First, update your package list to ensure you have the latest information on available packages:
sudo apt update
Step 2: Install Required Dependencies
Next, install the necessary dependencies for PHP:
sudo apt install software-properties-common
This package allows you to manage software repositories easily.
Step 3: Add the PHP Repository
To install PHP 8.4, you need to add the repository that contains it. Use the following command:
sudo add-apt-repository ppa:ondrej/php
After adding the repository, update your package list again:
sudo apt update
Step 4: Install PHP 8.4 and Extensions
Now, you can install PHP 8.4 along with some commonly used extensions. Run the following command:
sudo apt install php8.4 php8.4-zip php8.4-xml php8.4-gd php8.4-mysql php8.4-pgsql php8.4-intl php8.4-curl
