How to add PHP 8.1.24 to Ubuntu 22.04

You’re running the default PHP 8.1.22 on Ubuntu 22.04 and need to update to 8.1.24. Fortunately, the ondrej/php repository includes 8.1.22 so you can just remove the existing php, add ondrej/php and then install 8.1.24.

Check version on Ubuntu

php -v
> PHP 8.1.2-1ubuntu2.14 (cli) (built: Aug 18 2023 11:41:11) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
    with Zend OPcache v8.1.2-1ubuntu2.14, Copyright (c), by Zend Technologies

php -v | grep ^PHP | cut -d' ' -f2
> 8.1.2-1ubuntu2.14

Remove PHP

• Check if php is on hold. If it is, unhold it.

apt-mark showhold
apt-mark unhold php

• Now remove it

Note: we are keeping /etc/…php.ini because we want to keep the config file — no need to remove it. Also, I’m not using -y. The output of the remove will show what PHP modules are installed for reference. Copy these to a txt doc to make it easy to re-install. If you want a complete list of all modules and dependencies you can do php -M.

apt remove php-common
apt update

You can purge, but be very careful of removing things you don’t want to remove.

apt purge php8.1*
apt update

• Install ondrej/php repository. I like to do install > update > upgrade > reboot

add-apt-repository ppa:ondrej/php
apt update
apt list --upgradeable
apt upgrade
reboot

Install PHP 8.1.24

This is just a sample list of modules needed.

apt install php8.1 php8.1-bz2 php8.1-cli php8.1-common php8.1-curl php8.1-gd php8.1-gmp php8.1-intl php8.1-mbstring php8.1-mcrypt php8.1-mysql php8.1-opcache php8.1-readline php8.1-soap php8.1-sqlite3 php8.1-uploadprogress php8.1-xml php8.1-xmlrpc php8.1-yaml 

php -v 

PHP 8.1.24 (cli) (built: Oct 6 2023 09:46:42) (NTS)
Copyright (c) The PHP Group

PHP 8.1.24 is now installed.

If you want to prevent automatic updates:

apt-mark hold php 
apt-mark showhold 

Check with phpinfo();
