note 125963 added to jsonserializable.jsonserialize

Json Serializable did not analyze the result to serialize child properties. We have to call them manually: <?php class A implements JsonSerializable { private B $b; public function __construct(B $b) { $this->b = $b;} public function jsonSerialize(): array { return [ 'b' => $this->b->jsonSerialize()]; } } class B { private string $foo = ''; public function __construct(string $foo) { $this->foo = $foo; } public function jsonSerialize(): array { return ['foo' => $this->foo]; } } $a = new A(new B('Hallo Welt')); var_dump(json_encode($a)); ?> results in: string(26) "{"b":{"foo":"Hallo Welt"}}" ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.242 (proxied: 131.117.152.84) ---- Manual Page -- http://php.net/manual/en/jsonserializable.jsonserialize.php Edit -- https://master.php.net/note/edit/125963 Del: integrated -- https://master.php.net/note/delete/125963/integrated Del: useless -- https://master.php.net/note/delete/125963/useless Del: bad code -- https://master.php.net/note/delete/125963/bad+code Del: spam -- https://master.php.net/note/delete/125963/spam Del: non-english -- https://master.php.net/note/delete/125963/non-english Del: in docs -- https://master.php.net/note/delete/125963/in+docs Del: other reasons-- https://master.php.net/note/delete/125963 Reject -- https://master.php.net/note/reject/125963 Search -- https://master.php.net/manage/user-notes.php
