Nextcloud box publish new Apache, PHP, MySQL to nextcloud box

How can new developed Apache, PHP, MySQL apps be published to nextcloud box? I develop using PHPRunner Enterprise which has FTP to publish apps. I have nextcloud box running on my network with a IP address I can access using putty ssh connection. Signing on to nextcloud I can also drag and drop files from the development system. I was able to add external connection to dropbox to start moving data to the nextcloud box.
