Note Submitter: itsacon at itsacon dot net ---- Be aware that the null coalesce operator (??) has a lower priority than most other operators, so parentheses are usually a good idea if the output is used in anything other than an assignment. <?php $var = 1; if ($var ?? 0 == 2) {} // will evaluate to true if (2 == $undefinedVar ?? 0) {} // will throw an error if (($var ?? 0) == 2) {} // will evaluate to false ?> https://www.php.net/manual/en/language.operators.precedence.php
