PHP fragment:
PHP片段：
<?php
//Convert to date
$datestr="2011-09-23 19:10:18";//Your date
$date=strtotime($datestr);//Converted to a PHP date (a second count)
//Calculate difference
$diff=$date-time();//time returns current time in seconds
$days=floor($diff/(60*60*24));//seconds/minute*minutes/hour*hours/day)
$hours=round(($diff-$days*60*60*24)/(60*60));
//Report
echo "$days days $hours hours remain<br />";
?>
Note the hour-round and no minutes/seconds consideration means it can be slightly inaccurate.
请注意以小时为单位，不考虑分钟/秒意味着它可能会稍微不准确。

This should seed your endeavor.
这应该是你努力的种子。
getdate(strtotime("2011-09-23 19:10:18"))
Full conversion:
完全转换：
$seconds = strtotime("2011-09-23 19:10:18") - time();
$days = floor($seconds / 86400);
$seconds %= 86400;
$hours = floor($seconds / 3600);
$seconds %= 3600;
$minutes = floor($seconds / 60);
$seconds %= 60;
echo "$days days and $hours hours and $minutes minutes and $seconds seconds";

as of PHP 5.3.0 you could use build-in Date object:
从 PHP 5.3.0 开始，您可以使用内置 Date 对象：
$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-13');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days');

The easiest way is improved answer from CountZero. I used this solution for counter for time remaining before expiration of offer. Addition to first three lines of CountZero code:
最简单的方法是从 CountZero 改进答案。我使用这个解决方案来计算报价到期前的剩余时间。除了前三行 CountZero 代码：
$days = $interval->d;
$hours = $interval->h;
$minutes = $interval->i;
$seconds = $interval->s;
And now, you can use string functions to moderate your return values, to merge all or add '0' or '00' in front of the values.
现在，您可以使用字符串函数来调节返回值、合并所有值或在值前添加“0”或“00”。

it would be something like
它会是这样的
echo $date = date("Y-m-d H:i:s");echo "\n";
$original=time($date);
$modified = "2011-09-23 19:10:18";
echo date("Y-m-d H:i:s",$modified);echo "\n";

You can find current date and time using date() function and then subtract
您可以使用 date() 函数查找当前日期和时间，然后减去
$x = 2011-09-23 - current_date
$x = 2011-09-23 - current_date
this will give you no. of days left.
这会给你没有。剩下的天数。
Do same with time as well ..
时间也一样..
Hope this helps
希望这可以帮助
