PHP 8.1 Installation Guide

This document is the PHP 8.1 entry point and keeps the legacy guide unchanged.

• Legacy guide (unchanged): readme-php7.4.md
• Full PHP 8.1 setup and troubleshooting: ../readme-php.md

Quick Install (Ubuntu)

sudo apt update -y
sudo apt install -y php8.1 php8.1-common php8.1-cli php8.1-opcache php8.1-gd php8.1-curl php8.1-mysql php8.1-sqlite3

Restart Services

sudo systemctl restart php8.1-fpm
sudo systemctl restart nginx

Notes

• If you compile PHP from source or need pdo_sqlite troubleshooting, follow the complete instructions in ../readme-php.md.
• This file exists so PHP 8.1 documentation can evolve independently from the PHP 7.4 guide.
