How do I Set Up Virtual-Host-Specific PHP?

By default virtual hosts inherit the version of PHP that is set at the server level. You may wish to use a different PHP version for certain virtual hosts. Follow the steps below to set up virtual-host-level PHP. Here we will use the PHP version 7.4 as an example.

Install PHP 7.4 and commonly used PHP extensions: 

apt install lsphp74 lsphp74-common lsphp74-curl lsphp74-imagick lsphp74-imap lsphp74-json lsphp74-memcached lsphp74-mysql lsphp74-opcache lsphp74-redis -y
