empty() has very many uses. Once you understand what it is shorthand for, it makes a lot of sense to
use it how it was meant to be used. For example:

empty($var) ?: foo($var);

which is just shorter than:

if (isset($var) && $varl != false) {
  foo($bool);
}

Generally, you don't use empty() on strings though, just arrays, in my style guides anyway. For
strings, you use $string == "" or to be more proper, maybe 

trim($value ?? '') == ''

... but these days, trim doesn't accept null, so that makes it a bit more wordy
than it really should be. However, it is just a deprecation notice, so it is easy to ignore. For
now.
