Edit report at https://bugs.php.net/bug.php?id=60924&edit=1 ID: 60924 Updated by: cmb@php.net Reported by: chris at cmbuckley dot co dot uk Summary: ArrayObject should implement JsonSerializable interface -Status: Assigned +Status: Closed Type: Feature/Change Request Package: SPL related PHP Version: 5.4.0RC6 Assigned To: cmb Block user comment: N Private report: N New Comment: Thanks for the swift reply! :) Previous Comments: ------------------------------------------------------------------------ [2020-12-07 18:02:59] chris at cmbuckley dot co dot uk Casting my mind back to the intention 8 years ago, I believe the idea was flawed. I think my thought was something along the lines of "if something can be JSON-serialised, it should implement JsonSerializable". Though as you say, all PHP objects can be JSON-serialised, so application code should transparently use json_encode($obj) and a class should only use JsonSerializable if it should customise the JSON output. Feel free to close the ticket. ------------------------------------------------------------------------ [2020-12-07 15:41:04] cmb@php.net Being able to be json_encode()d, is the standard behavior of PHP objects. Why should ArrayObject implement JsonSerializable? ------------------------------------------------------------------------ [2012-01-29 17:45:37] chris at cmbuckley dot co dot uk Description: ------------ PHP 5.4 brings the new JsonSerializable interface. ArrayObject already works with json_encode as expected but does not explicitly implement this interface. Test script: --------------- $ao = new ArrayObject(array('foo' => 'bar')); var_dump(json_encode($ao)); var_dump($ao instanceof JsonSerializable); var_dump($ao->jsonSerialize()); Expected result: ---------------- string(13) "{"foo":"bar"}" bool(true) string(13) "{"foo":"bar"}" Actual result: -------------- string(13) "{"foo":"bar"}" bool(false) PHP Fatal error: Call to undefined method ArrayObject::jsonSerialize() in - on line 6 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60924&edit=1
