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>
I hope this article will be helpful to everyone’s PHP programming design.
