Question

I need a constant that can be called from every php page.
So, for example, I declare this constant somewhere, $APP_VERSION = "5.5".

Then I would like to call this variable from any pages. how to do this?

Answer 1

define('APP_VERSION', '5.5');

You can put that in the file that would be included into your pages. I’n that way you’d access it by APP_VERSION

echo APP_VERSION; //outputs 5.5
