Php获取当前日期时间:如何在PHP中获取当前日期和时间

哪个 PHP 函数可以返回当前日期 / 时间?

706

时间将随服务器时间变化。一种简单的解决方法是在调用date()time()函数之前,使用date_default_timezone_set手动设置时区。

我在墨尔本,Australia所以我有这样的东西:

date_default_timezone_set('Australia/Melbourne');

或者另一个例子是 LA-US

date_default_timezone_set('America/Los_Angeles');

您还可以通过以下方式查看服务器当前所在的时区:

date_default_timezone_get();

所以像这样:

$timezone = date_default_timezone_get();
echo "The current server timezone is: " . $timezone;

所以你的问题的简短答案是:

// Change the line below to your timezone!
date_default_timezone_set('Australia/Melbourne');
$date = date('m/d/Y h:i:s a', time());

然后所有的时间将是你刚刚设置的时区:)

// Simply:
$date = date('Y-m-d H:i:s');
// Or:
$date = date('Y/m/d H:i:s');
// This would return the date in the following formats respectively:
$date = '2012-03-06 17:33:07';
// Or
$date = '2012/03/06 17:33:07';
/** 
 * This time is based on the default server time zone.
 * If you want the date in a different time zone,
 * say if you come from Nairobi, Kenya like I do, you can set
 * the time zone to Nairobi as shown below.
 */
date_default_timezone_set('Africa/Nairobi');
// Then call the date functions
$date = date('Y-m-d H:i:s');
// Or
$date = date('Y/m/d H:i:s');
// date_default_timezone_set() function is however
// supported by PHP version 5.1.0 or above.

有关时区引用,请参阅List of Supported Timezones

由于 PHP5.2.0,您可以使用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timezone

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

由于夏令时,这可能比简单地将一天或一个月中的秒数添加或减去时间戳更可靠。

PHP 代码

// Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the
// Mountain Standard Time (MST) Time Zone
$today = date("F j, Y, g:i a");                 // March 10, 2001, 5:16 pm
$today = date("m.d.y");                         // 03.10.01
$today = date("j, n, Y");                       // 10, 3, 2001
$today = date("Ymd");                           // 20010310
$today = date('h-i-s, j-m-y, it is w Day');     // 05-16-18, 10-03-01, 1631 1618 6 Satpm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.');   // it is the 10th day.
$today = date("D M j G:i:s T Y");               // Sat Mar 10 17:16:18 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h');     // 17:03:18 m is month
$today = date("H:i:s");                         // 17:16:18
$today = date("Y-m-d H:i:s");                   // 2001-03-10 17:16:18 (the MySQL DATETIME format)
