How to create a variable outside function but which should not be visible outside my php file?
I mean a global variable with single file scope. I don’t want to add the function name in global namespace which may clash tomorrow.
with PHP5.2 and below, you simply can’t do it. Once it’s global, it’s global.
but from 5.3 onwards, there is Namespacing, which allows different levels of scope.
