How to get current date/time as a date object in PHP
提问by McGarnagle
How do you get today's date, as a date object?
你如何获得今天的日期，作为日期对象？
I'm trying to compute the difference between some start date and today. The following will not work, because getdate()returns an array and not a date object:
我正在尝试计算某个开始日期和今天之间的差异。以下将不起作用，因为getdate()返回一个数组而不是日期对象：
$today = getdate();
$start = date_create('06/20/2012');
$diff = date_diff($start, $today);
echo($today . '<br/>' . $start . '<br/>' . $diff);
Output:
输出：
Array ( [seconds] => 8 [minutes] => 1 [hours] => 16 [mday] => 11 [wday] => 1 [mon] => 6 [year] => 2012 [yday] => 162 [weekday] => Monday [month] => June [0] => 1339455668 )
DateTime Object ( [date] => 2012-06-20 00:00:00 [timezone_type] => 3 [timezone] => America/Los_Angeles )
数组 ( [seconds] => 8 [minutes] => 1 [hours] => 16 [mday] => 11 [wday] => 1 [mon] => 6 [year] => 2012 [yday] => 162 [工作日] => 星期一 [月] => 六月 [0] => 1339455668)
日期时间对象（ [date] => 2012-06-20 00:00:00 [timezone_type] => 3 [timezone] => America/Los_Angeles）

new DateTime('now');

Comparing is easy:
比较很简单：
$today = new DateTime('now');
$newYear = new DateTime('2012-01-01');
if ($today > $newYear) {
}
Op's editI just needed to call date_default_timezone_set, and then this code worked for me.
Op 的编辑我只需要调用date_default_timezone_set，然后这段代码对我有用。

To get difference in days use this:
要获得天数差异，请使用以下命令：
$today = new DateTime('today');
the time in this object eill be 00:00:00
此对象中的时间为 00:00:00
If you want difference with hours minutes and seconds use this:
如果您想要时分和秒的差异，请使用以下命令：
$now = new DateTime('now');

I ended up using the date_createconstructor (no parameter) to get the current date.
我最终使用date_create构造函数（无参数）来获取当前日期。
$diff = date_diff(date_create('06/20/2012'), date_create());
print_r($diff);
Output:
输出：
DateInterval Object ( [y] => 0 [m] => 0 [d] => 8 [h] => 6 [i] => 30 [s] => 40 [invert] => 1 [days] => 8 )
DateInterval 对象 ( [y] => 0 [m] => 0 [d] => 8 [h] => 6 [i] => 30 [s] => 40 [invert] => 1 [days] => 8)
I have no idea why, but Mike B's answer (and any constructor I tried for DateTime) threw an error for me in PHP5 / IIS.
我不知道为什么，但 Mike B 的回答（以及我为DateTime尝试的任何构造函数）在 PHP5/IIS 中为我抛出了一个错误。
