Is there a way to set the scope of require_once() explicitly to global?

Question

I\'m looking for a way to set the scope of require_once() to the global scope, when require_once() is used inside a function. Something like the follow

Answer 1

As the scope is explicitly defined where you use require and the like, you would need to specify what to do with the variables inside the scope of the function:

function includeFooFile() {
    require_once("foo.php"); // scope of "foo.php" will be the function scope

    foreach (get_defined_vars() as $k => $v)
    {
        $GLOBALS[$k] = &$v;
    }
}

This example takes care of both, variables and references which might be what you're looking for. Demo. Please note that require_once would only work once and would only define the variables once.
