3) So this leaves a function call which begs two questions: What do we call it, and what is the function syntax.
(a) What do we call it
We have a function that pretty much serves the same purpose: makeset($var, 'default').
The name was born because this function was made to replace a list of statements that make sure a variable is set:
if (!isset($_REQUEST['foo'])) $_REQUEST['foo'] = 0;
This is a function that takes its first argument by reference btw...
But my point was the name, maybe some of you might like it :).
