Apologies, it should be:
$counts[$item] = ($counts[$item] ?? 0) + 1;
Which both works, and to me, is more readable than the @ version
As with the file-manipulation functions, I think you're focussing too
much on the specific example and not on the general principle.
If we go through every single Notice and Warning discussing its
implications, when you might want to suppress it, when it should be
considered fatal, etc, we'll be here forever.
If there is even one Notice or Warning which is - subjectively - (a)
useful, and (b) non-fatal if ignored, then "turn everything into an
exception" is not a complete solution.
