Para poderem ter o php 7.3 no Debian 9, terão de utilizar um repositório de terceiros, neste caso do sury.
Vamos então começar, para tal vamos actualizar a lista de repositórios, executando:
# apt-get update
Agora, vamos instalar os pacotes necessários, correndo o seguinte commando:
# apt-get install ca-certificates apt-transport-https
Estamos então em condições para ir buscar o certificado do repositório:
# wget -q https://packages.sury.org/php/apt.gpg -O- | apt-key add -
Vamos então adicionar o caminho para o novo repositório
# echo "deb https://packages.sury.org/php/ stretch main" | tee /etc/apt/sources.list.d/php.list
Agora basta-nos actulizar novamente a lista de repositório e instalar a versão do php, bem como as suas extensões:
# apt-get update && apt-get install php7.3 php7.3-cli php7.3-fpm php7.3-mysql php7.3-intl php7.3-curl php7.3-json
Pronto, temos então a versão 7.3 do php instalada no nosso servidor.
