[DEBIAN] php 8.1 for debian stretch - fourslickz/notes GitHub Wiki

For older Debian version like stretch, I solved it by adding this repository

deb http://mirror-bbg-5.internet1.de/sury-php-stretch stretch main

in the following file

/etc/apt/sources.list.d/php.list

Then added the repository key

wget -qO - https://debian.octopuce.fr/sury-php/apt.gpg | apt-key add -
apt update
apt install php8.1-{bcmath,bz2,cgi,cli,common,curl,fpm,gd,gmp,imagick,intl,mbstring,mcrypt,memcache,memcached,mysql,readline,soap,uuid,xml,zip}
