示例

示例 #1 MongoDB\BSON\fromJSON() example

<?php

$json = '{ "_id": { "$oid": "563143b280d2387c91807965" } }';
$bson = MongoDB\BSON\fromJSON($json);
$value = MongoDB\BSON\toPHP($bson);
var_dump($value);

?>

以上示例会输出：

object(stdClass)#2 (1) {
  ["_id"]=>
  object(MongoDB\BSON\ObjectId)#1 (1) {
    ["oid"]=>
    string(24) "563143b280d2387c91807965"
  }
}
