Answer 1

The code you're using is a nested ternary expression. The form you have is a PHP idiom, but because it can be ambiguous its use is now prohibited. If you add appropriate parentheses to remove the ambiguity you'd be fine.

You could add the required parentheses, but there's a better way - use a spaceship operator.

Replace all of

return ($aLength == $bLength)
                                ? 0
                                : ($aLength < $bLength) ? -1 : 1;

with

return ($aLength <=> $bLength);
