PHP根据函数计算工作日的日期
我正在使用此函数(我在本论坛上找到)计算以下范围之间的工作日数:PHP根据函数计算工作日的日期,php,function,date,Php,Function,Date,我正在使用此函数(我在本论坛上找到)计算以下范围之间的工作日数: <?php //The function returns the no. of business days between two dates and it skips the holidays function getWorkingDays($startDate,$endDate,$holidays){ // do strtotime calculations just once $endDate = strtotime(
<?php
//The function returns the no. of business days between two dates and it skips the holidays
function getWorkingDays($startDate,$endDate,$holidays){
// 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 += $no_remaining_days;
}
//We subtract the holidays
foreach($holidays as $holiday){
$time_stamp=strtotime($holiday);
//If the holiday doesn't fall in weekend
if ($startDate <= $time_stamp && $time_stamp <= $endDate && date("N",$time_stamp) != 6 && date("N",$time_stamp) != 7)
$workingDays--;
}
return $workingDays;
}
//Example:
$holidays=array("2008-12-25","2008-12-26","2009-01-01");
echo getWorkingDays("$startdate","$enddate",$holidays)
?>
而
$startdate
是2012-06-01
我想让这个函数计算startdate+20个工作日将是2012-06-28。这可能吗?不久前,我使用下面的函数做了类似的事情。这里的关键是跳过周末,你也可以扩展到跳过假期
例如:
调用函数->addDays(strotime($startDate),20,$skipdays,$skipdates=array())
[编辑]:刚刚阅读了一篇关于Netuts的精彩文章,希望这能有所帮助如果有人感兴趣,我正在使用此功能为日期添加X个工作日。函数接受时间戳并返回时间戳。可以通过数组指定假日(如果在美国,可以使用
usBankHolidays()
)
目前,假设周六和周日不是工作日,但这很容易改变
代码:
function addBusinessDays($date, $days, $holidays = array()) {
$output = new DateTime();
$output->setTimestamp($date);
while ($days > 0) {
$weekDay = $output->format('N');
// Skip Saturday and Sunday
if ($weekDay == 6 || $weekDay == 7) {
$output = $output->add(new DateInterval('P1D'));
continue;
}
// Skip holidays
$strDate = $output->format('Y-m-d');
foreach ($holidays as $s) {
if ($s == $strDate) {
$output = $output->add(new DateInterval('P1D'));
continue 2;
}
}
$days--;
$output = $output->add(new DateInterval('P1D'));
}
return $output->getTimestamp();
}
function usBankHolidays($format = 'datesonly') {
$output = array(
array('2015-05-25', 'Memorial Day'),

);
if ($format == 'datesonly') {
$temp = array();
foreach ($output as $item) {
$temp[] = $item[0];
}
$output = $temp;
}
return $output;
}
用法:
$deliveryDate = addBusinessDays(time(), 7, usBankHolidays());
使用this.lau,我被缩写为反转它,用于减法日期,用于使用到期日期。希望这对某人有所帮助:
function subBusinessDays( $date, $days, $holidays = array() ) {
$output = new DateTime();
$output->setTimestamp( $date );
while ( $days > 0 ) {
$output = $output->sub( new DateInterval( 'P1D' ) );
// Skip holidays
$strDate = $output->format( 'Y-m-d' );
if ( in_array( $strDate, $holidays ) ) {
// Skip Saturday and Sunday
$output = $output->sub( new DateInterval( 'P1D' ) );
continue;
}
$weekDay = $output->format( 'N' );
if ($weekDay <= 5 ) {
$days --;
}
}
return $output->getTimestamp();
}
函数subBusinessDays($date,$days,$holidays=array()){
$output=新的日期时间();
$output->setTimestamp($date);
而($days>0){
$output=$output->sub(新的日期间隔('P1D'));
//跳过假期
$strDate=$output->format('Y-m-d');
if(在数组中($strDate,$holidays)){
//跳过周六和周日
$output=$output->sub(新的日期间隔('P1D'));
继续;
}
$weekDay=$output->format('N');
if($weekDay getTimestamp();
}
来自@this.lau uuu回答一个重写更简单、更逻辑的算法,带有动态(固定)holyday
使用
$deliveryDate = addBusinessDays(time(), 7);
我有一个更好的解决方案,函数上只有两个参数 只需调用函数
addDays($currentdate, $WordkingDatestoadd);
然后,使用下面的函数
function addDays($timestamp, $days) {
$workingDays = [1, 2, 3, 4, 5]; # date format = N (1 = Monday, ...)
$holidayDays = ['*-12-25', '*-01-01']; # variable and fixed holidays
$timestamp = new DateTime($timestamp);
$days = $days;
for($i=1 ; $i <= $days; $i++){
$timestamp = $timestamp->modify('+1 day');
if ((!in_array($timestamp->format('N'), $workingDays)) && (!in_array($timestamp->format('*-m-d'), $holidayDays))){
$i--;
}
}
$timestamp = $timestamp->format('Y-m-d');
return $timestamp;
}
function addDays($timestamp,$days){
$workingDays=[1,2,3,4,5];#日期格式=N(1=周一,…)
$holidayDays=['*-12-25','*-01-01'];#可变假日和固定假日
$timestamp=新日期时间($timestamp);
$days=$days;
对于($i=1;$i修改(“+1天”);
如果(!in_数组($timestamp->format('N'),$workingDays))&(!in_数组($timestamp->format('*-m-d'),$holidayDays))){
$i--;
}
}
$timestamp=$timestamp->format('Y-m-d');
返回$timestamp;
}
在这里,我将HolidayAPI动态用于假日列表。HolidayAPI可以自由实现。我是孟加拉国人,这就是我使用国家代码BD的原因。
API链接-
//卷曲开始
$cURLConnection=curl_init();
curl_setopt($cURLConnection,CURLOPT_URL,“您的api”);
curl_setopt($cURLConnection,CURLOPT_RETURNTRANSFER,true);
$phoneList=curl\u exec($cURLConnection);
卷曲关闭($卷曲连接);
$dateResponse=json_decode($phoneList);
//卷曲端
$holidays=array();//清除假日数组`在此处输入代码`
对于($i=0;$iholidays);$i++){
$holidays[]=$dateResponse->holidays[$i]->date;//从api在数组中插入假日
}
$startDate=“2020-02-26”;//插入您喜欢的值
$timestamp=strottime($startDate);//将日期转换为时间
$weekends=数组(“星期五”、“星期六”);
$days=0;//初始化天数计数器
而第(1)款{//
$timestamp=STROTIME(“+1天,$timestamp);//天增量
if((在_数组中(日期($l),时间戳,$weekends))|(在_数组中(日期($Y-m-d,时间戳,$holidays))//检查周末和假日
{
继续;
}否则{
$days++``
如果($days>=5){//interval-5天后的工作日是多少
回显日期(“Y-m-d”,$timestamp);//打印预期输出
打破
}
}
}
输入:2020-02-26
输出:2020-03-05你能再解释一下如何使用它吗?我对PHP函数基本上是新手。调用函数->addDays(strotime($startDate),20,$skipdays,$skipdates=NULL);如果您发送$skipDays和$skipDates的空VAL就可以了,在这种情况下,由defauld Sat、sun发送,不会跳过任何额外的日期。我如何将时间戳内容Y转换为实际的Y-M-D日期?是的,我是一个新手。$startdate作为变量似乎有一些问题。。如果我手动使用
StrotTime(2012-06-01),它会起作用
但是strottime($startdate)
不要这样做。即使我echo$startdate;
它输出正确的日期…杂耍问题?你能做一个快速测试吗,你能做类型转换吗?do:$startdate=(字符串)$startdate;echo strottime($startdate);尝试使所有假期都动态:)foreach$holidays中有一个bug。continue在foreach范围内,而不是while范围内,您必须使用continue 2。不客气,我喜欢您的算法,我对它进行了一些小的修改。谢谢。这看起来是一个学习TDD的完美例子:)
