• Throws MongoDB\Driver\Exception\InvalidArgumentException if id is not a 24-character hexadecimal string.

范例

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

<?phpvar_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"
}
