这里选择的操作系统和 PHP 版本是，CentOS 7 和 PHP 8.0。

答案：
CentOS 7 provides PHP version 5.4 in its official repository

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

You want multiple versions which means using a Software Collection

The php80 collection is available in the remi-safe repository

Command to install:
yum install php80

Command to install additional packages:
yum install php80-php-xxx

Command to install testing packages:
yum --enablerepo=remi-test install php80-php-xxx

When a single version is installed, command in default path (/usr/bin/php) can be installed:
yum install php80-syspaths
