The first example above is:
<?php
while (list($key, $value) = each($arr)) {
if (!($key % 2)) { // skip odd members
continue;
}
do_something_odd($value);
}
?>
The comment could be misleading. The expression $key % 2 is true for odd values of $key, so the if
is true and the continue is executed when $key is even.
The comment could reasonably mean "for odd members, we skip the continue." But since I
associate running the continue with "skipping" the remainder of the loop, I would comment
this just the opposite way: "skip even members."
