什么是Javascript的Date.UTC命令的PHP等价物？

Question

我怎么能在PHP中说这个Javascript:

var ts=Date.UTC(1985,1,22);

Answer 1

PHP的在线文档非常有用:http://www.php.net/manual/en/ref.datetime.php

mktime需要ARGS hour,minute,second,month,day,year.

$ts = mktime(0, 0, 0, 1, 22, 1985);

Date.UTC返回毫秒,而mktime返回秒,所以如果你仍然需要毫秒,则乘以1000.

Answer 2

$date = new DateTime(NULL, new DateTimeZone('UTC'));
$date->setDate(1985, 1, 22);
$ts = $date->getTimestamp();

编辑:更正时区参数.
