<?php
$wc = new MongoDB\Driver\WriteConcern(2, 1000, true);
var_dump($wc->bsonSerialize());
echo "\n", MongoDB\BSON\Document::fromPHP($wc)->toRelaxedExtendedJSON();
?>
The above example will output
something similar to:
object(stdClass)#2 (3) {
["w"]=>
int(2)
["j"]=>
bool(true)
["wtimeout"]=>
int(1000)
}
{ "w" : 2, "j" : true, "wtimeout" : 1000 }
