You simply suppressed the error in PHP 5. In PHP 7 the error classification changed, so you're no longer suppressing it. See: https://3v4l.org/2R8Vp Prior to the PHP 7 release I suggested marking a number of functions (array_pop/shift, reset, end) as prefer-ref, so they could be used without warning, see http://markmail.org/message/peefyi46iz2amdbq. Nothing really came of it at the time. Just mentioning it here because we can already avoid the warning right now -- we don't have to drop the IAP first. Both issues are independent. However, introducing array_first/last is still better than using reset/end etc, because these functions can easily trigger an unnecessary array copy, while array_first/last wouldn't have that problem.
