Why is $userid not globally set?

Question

I am seeing myself using

$userid = qa_get_logged_in_userid();

over and over again.

It would be easier to have this data "globally" accessible as $userid.

Is that possible?

Answer 1

Global variables are generaly regarded as bad coding. I'm actually looking to remove globals where possible.

And I don't think using globals will help anyway, because you would still need to do `global $userid` any time before you use it.

The good thing about using the function is that if the method of getting the user changed, you won't need to change your code.
