范例

Example #1 MongoDB\BSON\ObjectId::__construct() example

<?php

var_dump
(new MongoDB\BSON\ObjectId());

var_dump(new MongoDB\BSON\ObjectId('000000000000000000000001'));

?>

以上例程的输出类似于:

object(MongoDB\BSON\ObjectId)#1 (1) {
  ["oid"]=>
  string(24) "56732d3dda14d81214634921"
}
object(MongoDB\BSON\ObjectId)#1 (1) {
  ["oid"]=>
  string(24) "000000000000000000000001"
}

If you pass NULL to the __construct() method, it wont throw exceptions, nor errors, but prematurely ends the PHP processing (so it produced an 502 response over nginx), not like the legacy MongoId class.
