MongoDB\BSON\UTCDateTime::__construct

(mongodb >=1.0.0)

MongoDB\BSON\UTCDateTime::__constructConstruct a new UTCDateTime

说明

final public MongoDB\BSON\UTCDateTime::__construct(int|float|string|DateTimeInterface|null $milliseconds = null)

参数

milliseconds (int|float|string|DateTimeInterface|null)

Number of milliseconds since the Unix epoch (Jan 1, 1970). Negative values represent dates before 1970. This value may be provided as a 64-bit int. For compatibility on 32-bit systems, this parameter may also be provided as a float or string.

If the argument is a DateTimeInterface, the number of milliseconds since the Unix epoch will be derived from that value.

If this argument is null, the current time will be used by default.

错误/异常

更新日志

版本 说明
PECL mongodb 1.2.0

The milliseconds argument is optional and defaults to null (i.e. current time). The argument also accepts a DateTimeInterface, which may be used to derive the number of milliseconds since the Unix epoch. Previously, only int, float, and string types were accepted.

示例

示例 #1 MongoDB\BSON\UTCDateTime::__construct() example

<?php

var_dump
(new MongoDB\BSON\UTCDateTime);

var_dump(new MongoDB\BSON\UTCDateTime(new DateTime));

var_dump(new MongoDB\BSON\UTCDateTime(1416445411987));

?>

以上示例的输出类似于:

object(MongoDB\BSON\UTCDateTime)#1 (1) {
  ["milliseconds"]=>
  string(13) "1484852905560"
}
object(MongoDB\BSON\UTCDateTime)#1 (1) {
  ["milliseconds"]=>
  string(13) "1484852905560"
}
object(MongoDB\BSON\UTCDateTime)#1 (1) {
  ["milliseconds"]=>
  string(13) "1416445411987"
}
