The Qlikview development approach let you connect any database that have ODBC or OLEDB drivers.
If you MySQL database is deployed at a remote server, you must ensure that remote connections are granted on server and the download mysql ODBC drivers, for example, Set the ODBC connection to you remote server and then connect on it by Qlikview.
AT Quick Intelligence, you will find the QvSource App, www.quickintelligence.co.uk/qvsource/
It promises connect with some API services to get data directly from web server. I guess that is not the case of PHPMyAdmin.
Hope this helps
