Php 在整个月内循环一个月中的几天

我正在构建多日历，我有一个水平界面：

我正在尝试运行一周中的几天

S、M、T、W、T、F、S

整个月，而不仅仅是图中的前7个月

绘制日历的函数：

//our case "SUN" 
if(AC_START_DAY=="sun"){
    for($k=0; $k<7; $k++){
        $weekday = mb_substr($lang["day_".$k.""],0,1,'UTF-8');
        $list_day_titles.='<li class="cal_weekday"> '.$weekday.'</li>';
    }
}
//If we chose Monday as start week.
else{
    if ($first_week_day == 0)   $first_week_day =7;
    for($k=1; $k<=7; $k++){
        if($k==7)   $weekday = mb_substr($lang["day_0"][0],0,1,'UTF-8');
        else        $weekday = mb_substr($lang["day_".$k.""],0,1,'UTF-8');
        $list_day_titles.='<li title="'.$lang["day_".$k.""].'"> '.$weekday.'</li>';
    }
}

已经定义

$month=sprintf("%02s",$month);
//  define vars
$today_timestamp    =   mktime(0,0,0,date('m'),date('d'),date('Y'));    #   current timestamp - used to check if date is in past
$this_month         =   getDate(mktime(0, 0, 0, $month, 1, $year));     #   convert month to timestamp
$first_week_day     = $this_month["wday"];                              #   define first weekday (0-6)
$days_in_this_month = cal_days_in_month(CAL_GREGORIAN,$month,$year);    #   define number of days in week
$day_counter_tot    =   0; #    count total number of days showin INCLUDING previous and next months - use to get 6th row of dates

看起来，

$lang[“day”.$k.“”]

只是在计算从0到6的天数。。我怎样才能在月底前完成is循环

---

注意：我尝试将

$k使用循环增加到30/31天

然后换这条线

$weekday = mb_substr($lang["day_".$k.""],0,1,'UTF-8');

到

这将为您提供每个星期天的0天

0 % 7 = 0 (sunday)
1 % 7 = 1 (monday)
...
7 % 7 = 0 (sunday again)
8 % 7 = 1 (monday again)

使用循环到30/31天

然后换这条线

$weekday = mb_substr($lang["day_".$k.""],0,1,'UTF-8');

到

这将为您提供每个星期天的0天

0 % 7 = 0 (sunday)
1 % 7 = 1 (monday)
...
7 % 7 = 0 (sunday again)
8 % 7 = 1 (monday again)

您可以使用此代码生成当月的所有日期

for ($date = strtotime(date('Y-m-01')); $date < strtotime(date('Y-m-t')); $date = strtotime("+1 day", $date)) {
        echo date("l-d", $date)."<br>";
    }

您可以使用此代码生成当前月份的所有日期

for ($date = strtotime(date('Y-m-01')); $date < strtotime(date('Y-m-t')); $date = strtotime("+1 day", $date)) {
        echo date("l-d", $date)."<br>";
    }

看起来你几乎做对了。
您只需要稍微修改代码，使其按您希望的方式工作。
您只需将代码更改为：

$number_of_days_in_the_future = 42; // Here you can put in the number of days for which you want to display the corresponding letter, and based on your screenshot that is 42
//our case "SUN" 
if(AC_START_DAY=="sun"){
    for($i=0; $i<$number_of_days_in_the_future; $i++){
        $k = $i % 7;
        $weekday = mb_substr($lang["day_".$k.""],0,1,'UTF-8');
        $list_day_titles.='<li class="cal_weekday"> '.$weekday.'</li>';
    }
}
//If we chose Monday as start week.
else{
    if ($first_week_day == 0)   $first_week_day =7;
    for($i=1; $i<=$number_of_days_in_the_future; $i++){
        $k = $i % 7;
        if($k==7)   $weekday = mb_substr($lang["day_0"][0],0,1,'UTF-8');
        else        $weekday = mb_substr($lang["day_".$k.""],0,1,'UTF-8');
        $list_day_titles.='<li title="'.$lang["day_".$k.""].'"> '.$weekday.'</li>';
    }
}

$number\u未来的天数=42；//在这里，您可以输入您希望显示相应字母的天数，并基于42的屏幕截图
//我们的案例“太阳”
如果（AC_开始日==“太阳”）{
因为（$i=0；$i看起来你几乎做对了。

对于（$i=0；$i开始使用这些函数时，需要知道它们处理的月份，以便它可以计算一个月内的五月天数，因此您可以将循环限制更改为正确的输出天数。开始使用这些函数时，需要知道它们处理的月份，以便它可以计算一个月内可能有几天，因此您可以将循环限制更改为正确的输出天数
