If $totals[$item] has been set you want to increment its value, not set
it to one, so it should be the other way around. The statement is also
better written as

$totals[$item] = isset($totals[$item]) ? $totals[$item] + 1 : 1;

In your version there are side effects inside the conditional expression
and you ignore the result of it which is considered somewhat bad
programming style.
