PHP：DateTime::createFromFormat() 带时区

Question

I want to convert date form from d/m/Y to Ymd with timezone offset. I am able to convert from d/m/Y to Ymd with this code:

$date = DateTime::createFromFormat('d/m/Y', $date);
$date = $date->format('Y-m-d');

But I am not sure how to add the timezone offset.

Answer 1

(PHP 5 >= 5.3.0) you actually enter the third parameter

public static DateTime DateTime::createFromFormat(string $format , string $time[, DateTimeZone $timezone])

$date = DateTime::createFromFormat('d/m/Y', $date, new DateTimeZone('Europe/Berlin'));

Answer 2

Just use DateTime::setTimeZone() :

$date = DateTime::createFromFormat('d/m/Y', $date);
$date->setTimeZone(new DateTimeZone('America/New_York'));
$date = $date->format('Y-m-d');
