Strict standards error
php
Solution
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.
Problem
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?
