sudo apt-get install apt-transport-https lsb-release ca-certificates
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php.list
- Update the package list:
sudo apt-get update
- Install PHP 7 and related modules:
sudo apt-get install php7.0 php7.0-fpm php7.0-common php7.0-cli php7.0-mysql php7.0-mbstring
