Be careful on performing null coalesce on typecasted properties. Enclose them in parenthesis <?php $foo = new StdClass; //(int) 23 $bar = $foo->bas ?? 23; var_dump($bar); $foo = new StdClass; //(int) 23 $bar = (int) ($foo->bas ?? 23); var_dump($bar); $foo = new StdClass; $bar = (int) $foo->bas ?? 23; //Notice: Undefined property: stdClass::$bas var_dump($bar); ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.168 (proxied: 112.199.74.154) ---- Manual Page -- http://php.net/manual/en/migration70.new-features.php Edit -- https://master.php.net/note/edit/124579 Del: integrated -- https://master.php.net/note/delete/124579/integrated Del: useless -- https://master.php.net/note/delete/124579/useless Del: bad code -- https://master.php.net/note/delete/124579/bad+code Del: spam -- https://master.php.net/note/delete/124579/spam Del: non-english -- https://master.php.net/note/delete/124579/non-english Del: in docs -- https://master.php.net/note/delete/124579/in+docs Del: other reasons-- https://master.php.net/note/delete/124579 Reject -- https://master.php.net/note/reject/124579 Search -- https://master.php.net/manage/user-notes.php
