您的国家时区:支持的时区列表

date_default_timezone_set('Asia/Kolkata');

$dateYmd = date('Y-m-d');
echo "Current Year Month Day: $dateYmd";

本年月日:2022-01-03

$datehms = date('h:i:s');
echo "Current Hour Minute Second: $datehms";

当前小时分秒:11:05:38

非常简单的

date_default_timezone_set('Asia/Kolkata');
$date = date('m/d/Y H:i:s', time());

// Set the default timezone to use. Available since PHP 5.1
date_default_timezone_set('UTC');


// Prints something like: Monday
echo date("l");

// Prints something like: Monday 8th of August 2016 03:12:46 PM
echo date('l jS \of F Y h:i:s A');

// Prints: July 1, 2016 is on a Saturday
echo "July 1, 2016 is on a " . date("l", mktime(0, 0, 0, 7, 1, 2016));

/* Use the constants in the format parameter */
// Prints something like: Wed, 25 Sep 2013 15:28:57 -0700
echo date(DATE_RFC2822);

// Prints something like: 2016-07-01T00:00:00+00:00
echo date(DATE_ATOM, mktime(0, 0, 0, 7, 1, 2000));

如果你想获得日期，如12-3-2016，分开每一天，月和年的值，然后复制粘贴以下代码:

$day = date("d");
$month = date("m");
$year = date("y");
print "date" . $day . "-" . $month . "-" . $year;

您可以使用$_SERVER['REQUEST_TIME']变量(自PHP 5.1.0起可用)或time()函数来获取当前的Unix时间戳。

从PHP 5.2.0开始，你可以使用DateTime()类:

use \Datetime;

$now = new DateTime();
echo $now->format('Y-m-d H:i:s');    // MySQL datetime format
echo $now->getTimestamp();           // Unix Timestamp -- Since PHP 5.3

并指定时区:

$now = new DateTime(null, new DateTimeZone('America/New_York'));
$now->setTimezone(new DateTimeZone('Europe/London'));    // Another way
echo $now->getTimezone();
