什么是Javascript的Date.UTC命令的PHP等价物？

Question

我怎么能说此Javascript在PHP中：

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

Answer 1

PHP的在线文档是非常有用的：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回报毫秒，而mktime回报秒，所以如果你还想毫秒，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。

Answer 3

$ts = gmmktime(0, 0, 0, 2, 22, 1985) * 1000
