我正在为我的兄弟婚礼创建一个网站。到目前为止一切进展顺利。但是,他希望在主页上举行婚礼倒计时;
婚礼前的时间:X个月,X天,X个小时。
我更愿意使用php来做这件事,但会对其他建议持开放态度。
如果你可以帮我提供编码的想法,或者只是指出相关材料,那将是有用的。
婚礼将于7月30日星期六举行。

如果您的计数器仅在页面刷新时显示,并且在加载页面后保持静态,那么PHP就可以了。
如果您需要在显示页面时刷新倒计时,则需要使用JavaScript。
就个人而言,我会选择已经实施的内容,例如that small script。

静态倒计时:
//A: RECORDS TODAY'S Date And Time
$today = time();
//B: RECORDS Date And Time OF YOUR EVENT
$event = mktime(0,0,0,12,25,2006);
//C: COMPUTES THE DAYS UNTIL THE EVENT.
$countdown = round(($event - $today)/86400);
//D: DISPLAYS COUNTDOWN UNTIL EVENT
echo "$countown days until Christmas";
?>

以下是我从W3Schools网站复制的代码段,同时添加了我的PHP代码以获得"倒计时#34;时间戳和"现在"时间戳。
你会看到我已经注释掉了原始的JavaScript代码并在两个地方用PHP代码替换了它,所以很清楚地知道两个选项之间的区别。
基本上,当您考虑服务器时间"在您的情况下更可靠,您可以采用PHP方法。

$Target_Date = 1699458858; //expire data
$Time_Left = $Target_Date - time();
$days = floor($Time_Left / (60*60*24));//day
$Time_Left %= (60 * 60 * 24);
$hours = floor($Time_Left / (60 * 60));//hour
$Time_Left %= (60 * 60);
$min = floor($Time_Left / 60);//min
$Time_Left %= 60;
$sec = $Time_Left;//sec
echo "$days days and $hours hours and $min min and $sec sec left";

我不会为此使用php(服务器端)。因为每次都需要刷新页面以查看计数。最好使用javascript(clientside),更具体的jquery(javascript框架)。并查找jquery插件,例如:http://keith-wood.name/countdown.html

如果你想要实时的东西,你需要使用客户端脚本,即JavaScript。
你可以在PHP中完成它,但它不会“动画化”:
$wedding = strtotime("2011-07-01 12:00:00+0400"); // or whenever the wedding is
$secondsLeft = $wedding - time();
$days = floor($secondsLeft / 60*60*24);
$hours = floor(($secondsLeft - $days*60*60*24) / 60*60);
echo "$days days and $hours hours left";
你可以在几个月内进行更多的数学计算,但它变得更模糊,因为一个月不是固定的时间。
另一种方法是使用date()
函数来挑选单个元素(小时,分钟,秒,日,月等)并使用翻转数学,但是这很麻烦效应”。
如果您需要JavaScript示例,请告诉我。不要打扰jQuery - 它是杀死蚊子的正典:)

试试这个
<?php
$target = mktime(0, 0, 0, 9, 25, 2011) ;//set marriage date
$today = time () ;
$difference =($target-$today) ;
$month =date('m',$difference) ;
$days =date('d',$difference) ;
$hours =date('h',$difference) ;
print $month." month".$days." days".$hours."hours left";
?>

试试这个
$wedding = strtotime("2014-02-20 12:00:00"); // or whenever the wedding is
$current=strtotime('now');
$diffference =$wedding-$current;
$days=floor($diffference / (60*60*24));
echo "$days days left";
答案 8 :(得分:0)
$wedding = strtotime("2011-07-01 12:00:00+0400"); // or whenever the wedding is
$secondsLeft = $wedding - time();
$days = floor($secondsLeft / 60*60*24);
$hours = floor(($secondsLeft - $days*60*60*24) / 60*60);
echo "$days days and $hours hours left";
用户Neil E. Pearson编写的代码无效,他忘记在其中写括号(),有效的解决方案是:
$wedding = strtotime("2011-07-01 12:00:00+0400"); // or whenever the wedding is
$secondsLeft = $wedding - time();
$days = floor($secondsLeft / (60*60*24)); // here the brackets
$hours = floor(($secondsLeft - ($days*60*60*24)) / (60*60)); // and here too
echo "$days days and $hours hours left";
