    You might find the following also appropriate:

    #!/bin/sh
# To add this repository please do:

if [ "$(whoami)" != "root" ]; then
    SUDO=sudo
fi

${SUDO} apt-get update
${SUDO} apt-get -y install apt-transport-https lsb-release ca-certificates curl
${SUDO} curl -sSLo /usr/share/keyrings/deb.sury.org-php.gpg https://packages.sury.org/php/apt.gpg
${SUDO} sh -c 'echo "deb [signed-by=/usr/share/keyrings/deb.sury.org-php.gpg] https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'
${SUDO} apt-get update

    For example, a Dockerfile:

    FROM debian:stable

# ...

# PHP 8.1
# --------------------------------
# Related: https://packages.sury.org/php/README.txt

RUN 
    DEBIAN_FRONTEND=noninteractive 
        apt-get update && 
        apt-get full-upgrade && 
        apt-get clean;

RUN 
    DEBIAN_FRONTEND='noninteractive' 
        apt-get update && 
        apt-get install -y -- 
            apt-transport-https lsb-release ca-certificates curl && 
        curl -sSLo '/usr/share/keyrings/deb.sury.org-php.gpg' 'https://packages.sury.org/php/apt.gpg' && 
        printf -- '%sn' "deb [signed-by=/usr/share/keyrings/deb.sury.org-php.gpg] https://packages.sury.org/php/ $( lsb_release -sc; ) main" > '/etc/apt/sources.list.d/php.list' && 
        apt-get update && 
        apt-get install -y 
            php8.1-fpm php8.1-bcmath php8.1-curl php8.1-mbstring php8.1-pdo php8.1-mysql php8.1-xml && 
        apt-get clean;

ENTRYPOINT [ "./entrypoint.sh" ]
CMD [ "php-fpm8.1" ]

    Just in case, currently, the main difference between relatively common Debian and Alpine Linux PHP extension installations is that the latter builds extensions (i.e. make, docker-php-extension-installer) and the former – uses pre-compiled binaries (e.g. Bullseye/amd64).

    Alpine versions are currently mostly used in the official PHP Docker registry, yet the above PPA for PHP (5.6, 7.0, 7.1, 7.2, 7.3, 7.4, 8.0 and 8.1) (ppa:ondrej/php) mostly by Ondřej Surý is quite known and trusted.

    I am a Debian Developer since year 2000, and I have been packaging PHP for Debian since PHP 5. That means the official packages in Debian and Ubuntu are either my work or they are based on my work. The PHP packages in my Ubuntu PPA and Debian DPA matches the official packages in Debian. Basically I am saying that you can’t get any closer than that.
