probably after running

add-apt-repository ppa:ondrej/php

remove the previous source by running

sudo add-apt-repository --remove ppa:ondrej/phpsudo apt update

You will need to edit your repository source file as follows:

sudonano /etc/apt/sources.list

and enter

deb https://ppa.launchpadcontent.net/ondrej/php/ubuntu jammy main

then run

sudoapt update

after which you should now be able to install your php version using 8.3 as an example

sudoaptinstallphp8.3

if you already have some other php installed, you may need to change to the version using

sudoupdate-alternatives--config php

and follow the prompt.

you may also consider installing the following extenstions

sudoaptinstallphp8.3-curl php8.3-gd php8.3-intl php8.3-simplexml php8.3-dom php8.3-mysql php8.3-mbstring php8.3-xml php8.3-gd php8.3-curl php8.3-mysqli php8.3-zip
