I know this is easy to do. Though I want to know if there is a way upload apps to mysql database and a way to display them without the coding showing just the app. In php or html either or. I know a little in Ajax if there is a way in that.
If you even have a thought how I can start this. I would appreciate it.
I expect there are a few reasons for storing an application in a database. Perhaps a user is permitted to design an app using JavaScript, and the code/template result is stored in a database row for future retrieval and rendering.
But, in the usual case, applications are stored on a filing system, and interact with the database. @gman has some good links to start reading up on.
