Where can i Find an online server for my app?

Question

Hi SoloLearn!
I am creating an application in which you can create levels and share them with other users of the app.
I have correctly implemented its operation through a local server using xampp, however I need it to work online, my question is: Where can I get an online server with access to myPHPAdmin free or low cost?
I just have to save two simple tables in the database.
Thank you!
