什麼是Javascript的Date.UTC命令的PHP等價物？

Question

我怎麼能說此Javascript在PHP中：

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

Answer 1

PHP的在線文檔是非常有用的：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回報毫秒，而mktime回報秒，所以如果你還想毫秒，乘以1000

Answer 2

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

編輯：更正時區參數。

Answer 3

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