note 130472 added to unitenum.cases

The Enum documentation says, "if a Backed Enum is serialized to JSON, it will be represented by its scalar value only, in the appropriate type." This means you can easily get a backed Enum's values for use in a JSON document using only the BackedEnum::cases() method: <?php enum Suits: string { case Hearts = 'Heart'; case Diamonds = 'Diamond'; case Clubs = 'Spade'; case Spades = 'Club'; } echo json_encode(Suits::cases()); ?> Results in this output: ["Heart","Diamond","Spade","Club"] ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 2604:3d09:567b:c531:4486:72e4:da03:5f30) ---- Manual Page -- https://php.net/manual/en/unitenum.cases.php Edit -- https://main.php.net/note/edit/130472 Del: integrated -- https://main.php.net/note/delete/130472/integrated Del: useless -- https://main.php.net/note/delete/130472/useless Del: bad code -- https://main.php.net/note/delete/130472/bad+code Del: spam -- https://main.php.net/note/delete/130472/spam Del: non-english -- https://main.php.net/note/delete/130472/non-english Del: in docs -- https://main.php.net/note/delete/130472/in+docs Del: other reasons-- https://main.php.net/note/delete/130472 Reject -- https://main.php.net/note/reject/130472 Search -- https://main.php.net/manage/user-notes.php
