How to run PHP on Hosting Controller

Hi all, Currently I am using HC. I have a website run by PHP, but when I upload data to hosting, I can not run the website.
Enabled PHP and has set index.php - default.php on the top.
To use PHP on the HC to what conditions?
I think the need to configure something more can be run with PHP Web.

Thank you very much!

First make sure that php is working fine with website, try to execute a test php script this will make sure if php working or not.

In case php test script working and website still not working then check the elements which require to execute your php script i.e mysql extension, db connection etc.
