note 125585 added to language.operators.comparison

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 ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.244 (proxied: 77.172.55.111) ---- Manual Page -- http://php.net/manual/en/language.operators.comparison.php Edit -- https://master.php.net/note/edit/125585 Del: integrated -- https://master.php.net/note/delete/125585/integrated Del: useless -- https://master.php.net/note/delete/125585/useless Del: bad code -- https://master.php.net/note/delete/125585/bad+code Del: spam -- https://master.php.net/note/delete/125585/spam Del: non-english -- https://master.php.net/note/delete/125585/non-english Del: in docs -- https://master.php.net/note/delete/125585/in+docs Del: other reasons-- https://master.php.net/note/delete/125585 Reject -- https://master.php.net/note/reject/125585 Search -- https://master.php.net/manage/user-notes.php
