哪个PHP函数可以返回当前日期/时间?
当前回答
// 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.

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。

PHP以秒为单位返回当前时间。你需要把它们格式化成你想要的任何格式。
<?php
// time() returns current time in seconds
$in_seconds = time();
// strftime - Format a local time/date according to locale settings
echo strftime("%m/%d/%y", $in_seconds);
?>
参考:http://php.net/manual/en/function.strftime.php
你可以:
$now = strtotime(date('Y-m-d H:i:s')); // = Now
完整的格式选项请参见文档:https://www.php.net/manual/en/function.date.php
$date = new DateTime('now', new DateTimeZone('Asia/Kolkata'));
echo $date->format('d-m-Y H:i:s');
更新
//Also get am/pm in datetime:
echo $date->format('d-m-Y H:i:s a'); // output 30-12-2013 10:16:15 am
对于日期格式,PHP date() Function很有用。
