debian11 使用apt安装php, 使php多版本共存

sudo apt update 
sudo apt install software-properties-common ca-certificates lsb-release apt-transport-https 
sudo sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list' 
wget -qO - https://packages.sury.org/php/apt.gpg | sudo apt-key add - 

 这里的https://packages.sury.org/php/apt.gpg  key过期了, 需要执行

apt-key adv --fetch-keys 'https://packages.sury.org/php/apt.gpg' > /dev/null 2>&1

rm /usr/share/ca-certificates/mozilla/DST_Root_CA_X3.crt
vi /etc/ca-certificates.conf
and remove
mozilla/DST_Root_CA_X3.crt
update-ca-certificates
