Is a function return value copied? If the value is an integer I suppose
it is but what about a string or an array? If you pass by reference is
the return value still copied?
For example, is this:
function foo(&$arr) {
$arr[] = "bar";
}
faster than this?
function foo(&$arr) {
$arr[] = "bar";
return $arr; // is this copied?
}
I'm working on some code that would be called to generate a cell in a
possibly large table and therefore a small difference in performance
may have a significant impact.
Thanks,
Mike
