MongoDB\BSON\UTCDateTime::__construct — Construct a new UTCDateTime

Descrierea

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

Parametri

milliseconds (int|float|string|DateTimeInterface)

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. Note that in versions of PHP versions before 7.1.0, DateTime and DateTimeImmutable objects constructed from the current time did not incorporate sub-second precision.

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

Erori/Excepții

Emite MongoDB\Driver\Exception\InvalidArgumentException în cazul erorilor la interpretarea argumentelor.

Istoricul schimbărilor

Versiune	Descriere
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.

Exemple

Example #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));

?>

Exemplul de mai sus va afișa ceva similar cu:

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"
}

For me to get it work with php 5.6 on an iis 7.5, it had to be a string

$utcdatetime = new MongoDB\BSON\UTCDateTime('1416445411987');

The problem with integer => string is only on 32 bit systems
