PHP’s method of calculating the start and end dates of the week on a specified date, php date
The example in this article describes how PHP calculates the start and end dates of the week on a specified date. Share it with everyone for your reference. The specific implementation method is as follows:
<html>
<head>
<title>计算一周开始结束日期</title>
</head>
<body>
<form method="post" action="./index.html" enctype="utf-8">
<table>
<tr><td>输入年份</td>
<td><input name="year" type="text" maxlength="4" /></td>
</tr>
<tr><td>输入月份</td>
<td><input name="month" type="text" maxlength="2" /></td>
</tr>
<tr><td>输入天</td>
<td><input name="day" type="text" maxlength="2" /></td>
</tr>
<tr><td colspan="2"><input type="submit" value="计算" />
</td></tr>
</table>
</form>
<?php
$time= $_POST[year].'-'.$_POST[month].'-'.$_POST[day].' 00:00:00';
echo('你输入的时间是：'.$time.'</br>');
$lastday=date("Y-m-d",strtotime("$time Sunday"));
echo('输入的时间星期第一天是：'.date("Y-m-d",strtotime("$lastday - 6 days")).'<br/>');
echo('输入的时间星期最后一天是：'.$lastday);
?>
</body>
</html>
