严格的标准错误

Question

The function parse_users returns an array.

I am doing the following in another function:

return reset($this->parse_users($records));

But I get a Strict Standards: Only variables should be passed by reference in...

Is it because I do a reset() on the function?

Do I have to do it this way:

$users = $this->parse_users($records);
return reset($users);

Or is something else?

Answer 1

That's it exactly. reset takes a reference to an array as a parameter, so it basically needs a real variable to reference -- even if it is a pass-by-reference value.
