Problem using database backup script

I’m trying to use a database backup php script called mysqldumper.net. This script works on a vps with just a LEMP setup but the script doesn’t work when I tried using on a vps that had a clean install of easyengine. The problem is it gives a blank page after entering database login details. I already checked if I’ve given the correct file permission. I think easyengine may have missing extensions that may be required for this database php script?

Why do you need a web based backup tool? Why don’t you run mysqldump at command line in order to backup your databases?

Cause it makes life easier for a newbie like me who is still new at using Linux. Anyway I think I found the solution which is to install php5-mysql extension but I don’t know how to do it with easyengine since it has installed two php versions
