说明

final public MongoDB\BSON\ObjectId::__construct(string $id = ?)

参数

id (string): A 24-character hexadecimal string. If not provided, the driver will generate an ObjectId.

错误／异常

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
Throws MongoDB\Driver\Exception\InvalidArgumentException if id is not a 24-character hexadecimal string.

范例

示例 #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.
