如何在php中获得上周的日期范围？ [英] how can I get last week' date range in php?

问题描述

$ p

看到我的代码如下：

 <？php 
函数get_last_week_dates（）{
 //如何获取上周的日期范围？ 
 // ex：today is 2014-2-8 
 //上周的周日期范围应为'2014-1-26〜2014-2-1'
} 
？> 
  

解决方案

您可以使用 strtotime（）

  $ previous_week = strtotime（ -  1周+1天）; 
 
 $ start_week = strtotime（last sunday midnight，$ previous_week）; 
 $ end_week = strtotime（next saturday，$ start_week）; 
 
 $ start_week = date（Y-m-d，$ start_week）; 
 $ end_week = date（Y-m-d，$ end_week）; 
 
 echo $ start_week。'。$ end_week; 
  

更新

更改代码以处理星期日。如果当天是星期天，那么 - 1周将是上个星期日，再次获得上一个星期日，那将是一周之后。

  $ previous_week = strtotime（ -  1周+1天）; 
  

此外，如果我们需要找到本周和下周日期
范围我们可以作为

本周 -

  $ d = strtotime（today ）; 
 $ start_week = strtotime（最后星期日午夜，$ d）; 
 $ end_week = strtotime（next saturday，$ d）; 
 $ start = date（Y-m-d，$ start_week）; 
 $ end = date（Y-m-d，$ end_week）; 
  

下周 -

  $ d = strtotime（+ 1周-1天）; 
 $ start_week = strtotime（最后星期日午夜，$ d）; 
 $ end_week = strtotime（next saturday，$ d）; 
 $ start = date（Y-m-d，$ start_week）; 
 $ end = date（Y-m-d，$ end_week）; 
  

how can I get last week' date range in php ?

see my codes bellow:

<?php 
    function get_last_week_dates(){
        // how can i get the date range last week ?
        // ex: today is 2014-2-8
        // the week date range of last week should be '2014-1-26 ~ 2014-2-1'
    }
?>

解决方案

You can use strtotime()

$previous_week = strtotime("-1 week +1 day");

$start_week = strtotime("last sunday midnight",$previous_week);
$end_week = strtotime("next saturday",$start_week);

$start_week = date("Y-m-d",$start_week);
$end_week = date("Y-m-d",$end_week);

echo $start_week.' '.$end_week ;

UPDATE

Changed the code to handle sunday. If the current day is sunday then - 1 week will be previous sunday and again getting previous sunday for that will go the one week back.

$previous_week = strtotime("-1 week +1 day");

In addition if we need to find the current week and next week date range we can do as

Current week -

$d = strtotime("today");
$start_week = strtotime("last sunday midnight",$d);
$end_week = strtotime("next saturday",$d);
$start = date("Y-m-d",$start_week); 
$end = date("Y-m-d",$end_week);  

Next Week -

$d = strtotime("+1 week -1 day");
$start_week = strtotime("last sunday midnight",$d);
$end_week = strtotime("next saturday",$d);
$start = date("Y-m-d",$start_week); 
$end = date("Y-m-d",$end_week);
