Question

我正在创建一个HTML表格，以两种不同的方式显示员工时间的分配。第一种方式是ajax更新的队列，显示当前员工在哪里完成。

第二种类型是用户可以输入过去的“分配”的表单。现在，因为我的业务是24/7我决定在mysql中将所有时间存储为Date-Times，所以我可以得到以下区别：

2013-04-11 21:59:29和2013-04-12 01:52:29

以下是填写的表格：

 <form action="mafs.php" method="post" id="form1" name="form1" class="">     

                    <table id="tbl_past_allocation">
                      <tr>
                        <td class="txt-right" style="font-size:11px;">Employee Name</td>
                        <td ><input placeholder=" John Doe" style="width:100px; border-radius:10px;" type="text" name="peename" id="peename" /></td>
                      </tr>
                      <tr>

                            </form>

我遇到了一些与此不同的问题。

首先，我很好奇什么格式最适合存储这种类型的时间。
用户在表单中输入此信息最简单的是什么？ 4个单独的输入然后将它们连接在一起？或2，只是要求他们以指定的格式输入？

Answer 1

我认为单独的输入是最用户友好且最不容易出错的，因为它们是所有选择框。然后将值汇总在一起，对我个人而言，将它们转换为时间戳。时间戳也是24/7兼容。：）

我总是使用unix时间戳来保存我的gmt日期。然后比较它们的简单数学。

<?php

//
// Some comparison stuff
//

// 1 day = 86400 seconds
// mktime returns a unix timestamp.
$date1 = mktime(0, 0, 0, 1, 1, 2013); // Jan. 1st, 2013
$date2 = mktime(0, 0, 0, 1, 15, 2013); // Jan. 15th, 2013

// Get the difference
$diff = ($date2 / 86400) - ($date1 / 86400); // 14

echo $diff;

//
// Some conversion stuff
//
// Use mktime([$hour, $min, $sec, $mon, $day, $year]) if you have 
// a specific date you want converted into a timestamp, else use 
// time(), which is the current timestamp.
//
// Convert to human readable format
// 
$datetime = date("H:i:sa - M jS, Y", $timestamp); // $timestamp optional

echo $datetime; // e.g. 4:23:46pm - Jan 1st, 2013

?>

P.S。不要混淆我使用＆＃34; unix＆＃34;使用mysql数据类型TIMESTAMP的时间戳。 unix时间戳是1970年1月1日以来经过的秒数（整数）（？我相信？）。

// MySQL TIMESTAMP数据类型。

The TIMESTAMP data type is used for values that contain both date and time parts.   
TIMESTAMP has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC.

如果我做了任何不正确的假设，请不要犹豫纠正我。谢谢！
