示例 #1 MongoDB\BSON\PackedArray::fromJSON() example

<?php

$json = '[ "foo", { "$numberInt" : "123" }, { "$numberLong" : "4294967295" }, { "$oid" : "56315a7c6118fd1b920270b1" } ]';
$packedArray = MongoDB\BSON\PackedArray::fromJSON($json);
var_dump($packedArray);

?>

以上示例会输出：

object(MongoDB\BSON\PackedArray)#1 (2) {
  ["data"]=>
  string(68) "MQAAAAIwAAQAAABmb28AEDEAewAAABIyAP////8AAAAABzMAVjFafGEY/RuSAnCxAA=="
  ["value"]=>
  array(4) {
    [0]=>
    string(3) "foo"
    [1]=>
    int(123)
    [2]=>
    int(4294967295)
    [3]=>
    object(MongoDB\BSON\ObjectId)#2 (1) {
      ["oid"]=>
      string(24) "56315a7c6118fd1b920270b1"
