backup a database from a phprunner application

Hello everyone, I want to make a backup of the database possible in a phprunner application. That's what I tried to do with this example:
https://asprunner.com/forums/topic/19399-how-to-create-a-dump-of-mysql-database-in-one-click?fbclid=IwAR34OYX3PbHc8IcUz5tIEWKlyHdSOiVptUkj06dn9EjtWcFLrkhRElygVwg

This works great on localhost, but not on the hosting server where apparently the "mysqldump" program is not present according to an employee of the web hoster. Is there any other way to backup a database in a phprunner application? Thanks for your help.
