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

Beschreibung

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

Parameter-Liste

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.

Fehler/Exceptions

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.

Changelog

Version	Beschreibung
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.

Beispiele

Beispiel #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));

?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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"
}
