<?php if (!extension_loaded("json")) print "skip"; ?>
--FILE--
<?php
$result = json_encode(['end' => json_decode(null, true)]);
var_dump($result);
class A implements \JsonSerializable
{
function jsonSerialize()
{
return ['end' => json_decode(null, true)];
}
}
$a = new A();
$toJsonData = $a->jsonSerialize();
$result = json_encode($a);
var_dump($result);
$result = json_encode($toJsonData);
var_dump($result);
