You must be using the latest version of CustomBuild 2.0.
The first PHP version will be the default and will run all webapps. Everything else is optional.
Users can select between versions on their “Domain Setup” page in DirectAdmin.
A sample install of multiple PHP versions:
cd /usr/local/directadmin/custombuild ./build update ./build set php1_release 7.1 ./build set php2_release 5.6 ./build set php3_release 7.0 ./build set php4_release 7.3 ./build set php1_mode php-fpm ./build set php2_mode php-fpm ./build set php3_mode php-fpm ./build set php4_mode php-fpm ./build php n ./build rewrite_confs
