Install LAMP- Apache, PHP 7.4 with Apache Handler on Debian 12

Well, it’s not perfectly a LAMP stack as MySQL and PHPMYadmin are not covered here. But for someone who needs a backward compatible php edition to work on a modern/latest os built.

Step1: Add PHP repository

We’ll use a bash script to add the repository-

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

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

${SUDO} apt-get update
${SUDO} apt-get -y install lsb-release ca-certificates curl
${SUDO} curl -sSLo /tmp/debsuryorg-archive-keyring.deb https://packages.sury.org/debsuryorg-archive-keyring.deb
${SUDO} dpkg -i /tmp/debsuryorg-archive-keyring.deb
${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

Step-2: Install PHP Modules

Install a few dependencies required by this tutorial with the below-mentioned command:

sudo apt install software-properties-common ca-certificates lsb-release apt-transport-https

Install PHP 7.4:

sudo apt install php7.4

if you want to add multiple extensions then include them in braces, I am going to install “php-mbstring, php-mysql, php-xml, and php-curl” by running the below-mentioned command:

sudo apt install php7.4-mysql php7.4-mbstring php7.4-xml php7.4-curl
