我想计算用户输入的总天差
例如当用户输入
start_date = 2012-09-06和end-date = 2012-09-11
现在我正在使用此代码来查找差异
$count = abs(strtotime($start_date) - strtotime($end_date));
$day = $count+86400;
$total = floor($day/(60*60*24));
总计的结果将是 6。但问题是我不想包括周末的日子（周六和周日）
2012-09-06
2012-09-07
2012-09-08 Saturday
2012-09-09 Sunday
2012-09-10
2012-09-11
所以结果将是 4
- - 更新 - -
我有一个包含日期的表格，表格名称是假期日期
例如该表包含2012-09-07
所以，总天数将是 3，因为它没有计算假期日期
我该怎么做才能将输入的日期等同于表中的日期？
我最喜欢的很容易DateTime：DateInterval和DatePeriod
$start = new DateTime('2012-09-06');
$end = new DateTime('2012-09-11');
// otherwise the end date is excluded (bug?)
$end->modify('+1 day');
$interval = $end->diff($start);
// total days
$days = $interval->days;
// create an iterateable period of date (P1D equates to 1 day)
$period = new DatePeriod($start, new DateInterval('P1D'), $end);
// best stored as array, so you can add more than one
$holidays = array('2012-09-07');
foreach($period as $dt) {
$curr = $dt->format('D');
// substract if Saturday or Sunday
if ($curr == 'Sat' || $curr == 'Sun') {
$days--;
}
// (optional) for the updated question
elseif (in_array($dt->format('Y-m-d'), $holidays)) {
$days--;
}
}
echo $days; // 4
就我而言，我需要与 OP 相同的答案，但想要更小的答案。@Bojan 的答案有效，但我不喜欢它不适用于DateTime对象，需要使用时间戳，并且是在与实际对象本身进行比较strings而不是实际对象本身（感觉很糟糕）......这是他答案的修订版。
function getWeekdayDifference(\DateTime $startDate, \DateTime $endDate)
{
$days = 0;
while($startDate->diff($endDate)->days > 0) {
$days += $startDate->format('N') < 6 ? 1 : 0;
$startDate = $startDate->add(new \DateInterval("P1D"));
}
return $days;
}
如果您希望这包括开始和结束日期，请根据@xzdead 的评论：
function getWeekdayDifference(\DateTime $startDate, \DateTime $endDate)
{
$isWeekday = function (\DateTime $date) {
return $date->format('N') < 6;
};
$days = $isWeekday($endDate) ? 1 : 0;
while($startDate->diff($endDate)->days > 0) {
$days += $isWeekday($startDate) ? 1 : 0;
$startDate = $startDate->add(new \DateInterval("P1D"));
}
return $days;
}
使用DateTime：
$datetime1 = new DateTime('2012-09-06');
$datetime2 = new DateTime('2012-09-11');
$interval = $datetime1->diff($datetime2);
$woweekends = 0;
for($i=0; $i<=$interval->d; $i++){
$datetime1->modify('+1 day');
$weekday = $datetime1->format('w');
if($weekday !== "0" && $weekday !== "6"){ // 0 for Sunday and 6 for Saturday
$woweekends++;
}
}
echo $woweekends." days without weekend";
// 4 days without weekends
在没有周末的情况下获得差异的最简单和最快的方法是使用Carbon库。
这是一个如何使用它的示例：
<?php
$from = Carbon\Carbon::parse('2016-05-21 22:00:00');
$to = Carbon\Carbon::parse('2016-05-21 22:00:00');
echo $to->diffInWeekdays($from);
date('N') 获取星期几（1 - 星期一，7 - 星期日）
$start = strtotime('2012-08-06');
$end = strtotime('2012-09-06');
$count = 0;
while(date('Y-m-d', $start) < date('Y-m-d', $end)){
$count += date('N', $start) < 6 ? 1 : 0;
$start = strtotime("+1 day", $start);
}
echo $count;
这是@dan-lee 函数的改进版本：
function get_total_days($start, $end, $holidays = [], $weekends = ['Sat', 'Sun']){
$start = new \DateTime($start);
$end = new \DateTime($end);
$end->modify('+1 day');
$total_days = $end->diff($start)->days;
$period = new \DatePeriod($start, new \DateInterval('P1D'), $end);
foreach($period as $dt) {
if (in_array($dt->format('D'), $weekends) || in_array($dt->format('Y-m-d'), $holidays)){
$total_days--;
}
}
return $total_days;
}
要使用它：
$start = '2021-06-12';
$end = '2021-06-17';
$holidays = ['2021-06-15'];
echo get_total_days($start, $end, $holidays); // Result: 3
看看这篇文章： 计算工作日
（在您的情况下，您可以省略“假期”部分，因为您仅在工作/工作日之后）
<?php
//The function returns the no. of business days between two dates
function getWorkingDays($startDate,$endDate){
// do strtotime calculations just once
$endDate = strtotime($endDate);
$startDate = strtotime($startDate);
//The total number of days between the two dates. We compute the no. of seconds and divide it to 60*60*24
//We add one to inlude both dates in the interval.
$days = ($endDate - $startDate) / 86400 + 1;
$no_full_weeks = floor($days / 7);
$no_remaining_days = fmod($days, 7);
//It will return 1 if it's Monday,.. ,7 for Sunday
$the_first_day_of_week = date("N", $startDate);
$the_last_day_of_week = date("N", $endDate);
//---->The two can be equal in leap years when february has 29 days, the equal sign is added here
//In the first case the whole interval is within a week, in the second case the interval falls in two weeks.
if ($the_first_day_of_week <= $the_last_day_of_week) {
if ($the_first_day_of_week <= 6 && 6 <= $the_last_day_of_week) $no_remaining_days--;
if ($the_first_day_of_week <= 7 && 7 <= $the_last_day_of_week) $no_remaining_days--;
}
else {
// (edit by Tokes to fix an edge case where the start day was a Sunday
// and the end day was NOT a Saturday)
// the day of the week for start is later than the day of the week for end
if ($the_first_day_of_week == 7) {
// if the start date is a Sunday, then we definitely subtract 1 day
$no_remaining_days--;
if ($the_last_day_of_week == 6) {
// if the end date is a Saturday, then we subtract another day
$no_remaining_days--;
}
}
else {
// the start date was a Saturday (or earlier), and the end date was (Mon..Fri)
// so we skip an entire weekend and subtract 2 days
$no_remaining_days -= 2;
}
}
//The no. of business days is: (number of weeks between the two dates) * (5 working days) + the remainder
//---->february in none leap years gave a remainder of 0 but still calculated weekends between first and last day, this is one way to fix it
$workingDays = $no_full_weeks * 5;
if ($no_remaining_days > 0 )
{
$workingDays += $no_remaining_days;
}
return $workingDays;
}
// This will return 4
echo getWorkingDays("2012-09-06","2012-09-11");
?>
如果您不需要全天但需要准确的秒数，请尝试使用此代码。这接受 unix 时间戳作为输入。
function timeDifferenceWithoutWeekends($from, $to) {
$start = new DateTime("@".$from);
$current = clone $start;
$end = new DateTime("@".$to);
$sum = 0;
while ($current<$end) {
$endSlice = clone $current;
$endSlice->setTime(0,0,0);
$endSlice->modify('+1 day');
if ($endSlice>$end) {
$endSlice= clone $end;
}
$seconds = $endSlice->getTimestamp()-$current->getTimestamp();
$currentDay = $current->format("D");
if ($currentDay != 'Sat' && $currentDay != 'Sun') {
$sum+=$seconds;
}
$current = $endSlice;
}
return $sum;
}
/**
* Getting the Weekdays count[ Excludes : Weekends]
*
* @param type $fromDateTimestamp
* @param type $toDateTimestamp
* @return int
*/
public static function getWeekDaysCount($fromDateTimestamp = null, $toDateTimestamp=null) {
$startDateString = date('Y-m-d', $fromDateTimestamp);
$timestampTomorrow = strtotime('+1 day', $toDateTimestamp);
$endDateString = date("Y-m-d", $timestampTomorrow);
$objStartDate = new \DateTime($startDateString); //intialize start date
$objEndDate = new \DateTime($endDateString); //initialize end date
$interval = new \DateInterval('P1D'); // set the interval as 1 day
$dateRange = new \DatePeriod($objStartDate, $interval, $objEndDate);
$count = 0;
foreach ($dateRange as $eachDate) {
if ( $eachDate->format("w") != 6
&& $eachDate->format("w") != 0
) {
++$count;
}
}
return $count;
}
请查看这个精确的 php 函数返回天数，不包括周末。
function Count_Days_Without_Weekends($start, $end){
$days_diff = floor(((abs(strtotime($end) - strtotime($start))) / (60*60*24)));
$run_days=0;
for($i=0; $i<=$days_diff; $i++){
$newdays = $i-$days_diff;
$futuredate = strtotime("$newdays days");
$mydate = date("F d, Y", $futuredate);
$today = date("D", strtotime($mydate));
if(($today != "Sat") && ($today != "Sun")){
$run_days++;
}
}
return $run_days;
}
试试看，确实有效。。
使用 Carbon\Caborn 的一个非常简单的解决方案
这是从控制器存储功能调用的存储库文件
<?php
namespace App\Repositories\Leave;
use App\Models\Holiday;
use App\Models\LeaveApplication;
use App\Repositories\BaseRepository;
use Carbon\Carbon;
class LeaveApplicationRepository extends BaseRepository
{
protected $holiday;
public function __construct(LeaveApplication $model, Holiday $holiday)
{
parent::__construct($model);
$this->holiday = $holiday;
}
/**
* Get all authenticated user leave
*/
public function getUserLeave($id)
{
return $this->model->where('employee_id',$id)->with(['leave_type','approver'])->get();
}
/**
* @param array $request
*/
public function create($request)
{
$request['total_days'] = $this->getTotalDays($request['start_date'],$request['end_date']);
return $this->model->create($request->only('send_to','leave_type_id','start_date','end_date','desc','total_days'));
}
/**
* Get total leave days
*/
private function getTotalDays($startDate, $endDate)
{
$holidays = $this->getHolidays(); //Get all public holidays
$leaveDays = 0; //Declare values which hold leave days
//Format the dates
$startDate = Carbon::createFromFormat('Y-m-d',$startDate);
$endEnd = Carbon::createFromFormat('Y-m-d',$endDate);
//Check user dates
for($date = $startDate; $date <= $endEnd; $date->modify('+1 day')) {
if (!$date->isWeekend() && !in_array($date,$holidays)) {
$leaveDays++; //Increment days if not weekend and public holidays
}
}
return $leaveDays; //return total days
}
/**
* Get Current Year Public Holidays
*/
private function getHolidays()
{
$holidays = array();
$dates = $this->holiday->select('date')->where('active',1)->get();
foreach ($dates as $date) {
$holidays[]=Carbon::createFromFormat('Y-m-d',$date->date);
}
return $holidays;
}
}
控制器函数接收用户输入请求并在调用存储库函数之前进行验证
<?php
namespace App\Http\Controllers\Leave;
use App\Http\Controllers\AuthController;
use App\Http\Requests\Leave\LeaveApplicationRequest;
use App\Repositories\Leave\LeaveApplicationRepository;
use Exception;
class LeaveApplicationController extends AuthController
{
protected $leaveApplication;
/**
* LeaveApplicationsController constructor.
*/
public function __construct(LeaveApplicationRepository $leaveApplication)
{
parent::__construct();
$this->leaveApplication = $leaveApplication;
}
/**
* Store a newly created resource in storage.
*/
public function store(LeaveApplicationRequest $request)
{
try {
$this->leaveApplication->create($request);
return $this->successRoute('leaveApplications.index','Leave Applied');
}
catch (Exception $e) {
return $this->errorWithInput($request);
}
}
}
这是计算两个日期之间的工作日的替代方法，并且还使用来自http://pear.php.net/package/Date_Holidays的 Pear 的 Date_Holidays 排除美国假期。
$start_date 和 $end_date 应该是 DateTime 对象（您可以new DateTime('@'.$timestamp)用来从时间戳转换为 DateTime 对象）。
<?php
function business_days($start_date, $end_date)
{
require_once 'Date/Holidays.php';
$dholidays = &Date_Holidays::factory('USA');
$days = 0;
$period = new DatePeriod($start_date, new DateInterval('P1D'), $end_date);
foreach($period as $dt)
{
$curr = $dt->format('D');
if($curr != 'Sat' && $curr != 'Sun' && !$dholidays->isHoliday($dt->format('Y-m-d')))
{
$days++;
}
}
return $days;
}
?>
