Use a standard if-else. The ternary operator ?: is *not*, repeat *not*,
a short-hand form for if() {...} else {...}.
It's designed to be used to evaluate a value that's dependent on some
condition, i.e.:
$result = ($test_expression) ? $val_if_true : $val_if_false;
Now, it just so happens that assignments (e.g. $do = true in your
example above) resolve to a value, and so can be used as $val_if_true or
$val_if_false. Don't let that fool you into thinking that you can
execute arbitrary blocks of code inside a ternary statement.
