例

例1 MongoDB\BSON\PackedArray::toCanonicalExtendedJSON example

<?php

$array = [
    'foo',
    123,
    4294967295,
    new MongoDB\BSON\ObjectId('56315a7c6118fd1b920270b1'),
];

$packedArray = MongoDB\BSON\PackedArray::fromPHP($array);
echo $packedArray->toCanonicalExtendedJSON(), "\n";

?>

上の例の出力は以下となります。

[ "foo", { "$numberInt" : "123" }, { "$numberLong" : "4294967295" }, { "$oid" : "56315a7c6118fd1b920270b1" } ]
