在这种情况下，我创建了一个员工的数据。我在PHP中使用了一个数组，并分配了变量，并将其称为Smarty，并在PHP的帮助下创建了一个表。在此，我想计算D.O.J和当前日期之间的天数。如何计算D.O.J和当前日期之间的天数。请帮助我。
PHP代码：
<?php
include_once "../prepengine-header.php";
$users = array(
1 => array(
'id' => '00AC',
'name' => 'john',
'address' => 'California',
'email' => 'JOHn@yAhOO.com',
'dob' => '1989/10/06',
'doj' => '2014/12/04'
),
2 => array(
'id' => '00XV',
'name' => 'brad',
'address' => 'Washington',
'email' => 'bRAd@gmail.com',
'dob' => '1980/09/23',
'doj' => '2005/03/10'
),
3 => array(
'id' => '00UY',
'name' => 'swati',
'address' => 'Mutthiganj',
'email' => 'SWAti@yahoo.com',
'dob' => '1990/05/04',
'doj' => '2013/01/02'
),
4 => array(
'id' => '002VC',
'name' => 'smith',
'address' => 'California',
'email' => 'SMITH@yahoo.com',
'dob' => '1989/10/22',
'doj' => '2013/07/15'
),
5 => array(
'id' => '00RK',
'name' => 'crystal',
'address' => 'New York',
'email' => 'crystal@GMAIL.com',
'dob' => '1991/05/28',
'doj' => '2015/01/15'
),
6 => array(
'id' => '00PC',
'name' => 'virat',
'address' => 'Vadodara',
'email' => 'VIraT@Yahoo.com',
'dob' => '1989/01/24',
'doj' => '2013/04/01'
),
);
$head[] = "Serial no.";
$head = array_merge($head, array_keys($users[1]));
$theme->assign('head', $head);
$theme->assign("table", $users);
echo($theme->fetch('smartart/p_screen5.tpl'));
?>
智能代码：
<html>
<head>
<title>Screen5</title>
<style>
table,tr, th, td, thead
{
border: 2px solid #333;
}
.rwd-table
{
width: 74%;
height: 77%;
text-align: center;
}
.rwd-table {
margin: 3em 10em;
min-width: 300px;
}
th{
height: 45px;
color: #ADFF2F;
}
body {
padding: 0 3em;
font-family: Montserrat, sans-serif;
color: #444;
background: #eee;
}
.rwd-table {
background: #34495E;
color: #fff;
border-radius: .4em;
overflow: hidden;
}
tr {
border-color: lighten(#34495E, 10%);
}
</style>
</head>
<body>
<form id="data_table" name="data_table">
<table class="rwd-table">
<thead>
<{foreach from = $head key = heading item = file}>
<th><{$file|upper}></th>
<{/foreach}>
</thead>
<{foreach from = $table key = heading item = file}>
<tr>
<td><{counter}></td>
<td><{$file.id}></td>
<td><{$file.name|ucfirst}></td>
<td><{$file.address}></td>
<td><{$file.email}></td>
<td><{$file.dob}></td>
<td><{$file.doj}></td>
</tr>
<{/foreach}>
</table>
</form>
</body>
</html>

我从您的代码中了解的是，在日期之间获得日期的简单解决方案是
function getDaysBetweenTwoDates($date1,$date2){
$date1 = date('y-m-d',strtotime($date1));
$date2 = date('y-m-d',strtotime($date2));
$now = new DateTime($date1);
$ago = new DateTime($date2);
$diff = $now->diff($ago);
return $diff->days;
}
只需通过此功能中的两个日期，例如这个
echo getDaysBetweenTwoDates('2017/08/01','2017/07/08'); //24
echo getDaysBetweenTwoDates('2017-08-01','2016-07-08'); //389
在这里您可以看到运行代码
执行以下操作：
PHP代码：
<?php
include_once "../prepengine-header.php";
$today = time();
$users = array(
1 => array(
'id' => '00AC',
'name' => 'john',
'address' => 'California',
'email' => 'JOHn@yAhOO.com',
'dob' => '1989/10/06',
'doj' => '2014/12/04',
'diff' => floor(($today - strtotime('2014/12/04')) / 86400)
),
2 => array(
'id' => '00XV',
'name' => 'brad',
'address' => 'Washington',
'email' => 'bRAd@gmail.com',
'dob' => '1980/09/23',
'doj' => '2005/03/10',
'diff' => floor(($today - strtotime('2005/03/10')) / 86400)
),
3 => array(
'id' => '00UY',
'name' => 'swati',
'address' => 'Mutthiganj',
'email' => 'SWAti@yahoo.com',
'dob' => '1990/05/04',
'doj' => '2013/01/02',
'diff' => floor(($today - strtotime('2013/01/02')) / 86400)
),
4 => array(
'id' => '002VC',
'name' => 'smith',
'address' => 'California',
'email' => 'SMITH@yahoo.com',
'dob' => '1989/10/22',
'doj' => '2013/07/15',
'diff' => floor(($today - strtotime('2013/07/15')) / 86400)
),
5 => array(
'id' => '00RK',
'name' => 'crystal',
'address' => 'New York',
'email' => 'crystal@GMAIL.com',
'dob' => '1991/05/28',
'doj' => '2015/01/15',
'diff' => floor(($today - strtotime('2015/01/15')) / 86400)
),
6 => array(
'id' => '00PC',
'name' => 'virat',
'address' => 'Vadodara',
'email' => 'VIraT@Yahoo.com',
'dob' => '1989/01/24',
'doj' => '2013/04/01',
'diff' => floor(($today - strtotime('2013/04/01')) / 86400)
),
);
$head[] = "Serial no.";
$head = array_merge($head, array_keys($users[1]));
$theme->assign('head', $head);
$theme->assign("table", $users);
echo($theme->fetch('smartart/p_screen5.tpl'));
?>
和您的形式：
<form id="data_table" name="data_table">
<table class="rwd-table">
<thead>
<{foreach from = $head key = heading item = file}>
<th><{$file|upper}></th>
<{/foreach}>
</thead>
<{foreach from = $table key = heading item = file}>
<tr>
<td><{counter}></td>
<td><{$file.id}></td>
<td><{$file.name|ucfirst}></td>
<td><{$file.address}></td>
<td><{$file.email}></td>
<td><{$file.dob}></td>
<td><{$file.doj}></td>
<td><{$file.diff}></td>
</tr>
<{/foreach}>
</table>
</form>
就是这样。
基本上我所做的是，我只是在每个数组中添加了一个新元素" diff"。并在PHP代码的顶部定义了一个新的变量$today。
和形式，我刚刚在表中添加了一个新的" TD"，其中包含代码{$file.diff}。它将在您的表格中打印差异。
请尝试一下。
