改进 php 日历脚本，未检测到下个月的日期

Question

我正在尝试改进日历 php 脚本，此时我可以看到一切正常，但除了 接下来几个月的日子 未在网格中检测到...！我试着自己解决这个问题，但我运气不好，所以如果有人能帮我修复这个脚本就太好了！

<?php 
  function calendar($file) {
    if ((isset($_GET['d'])) ? $day = $_GET['d'] : $day = date("d"));
    if ((isset($_GET['m'])) ? $month = $_GET['m'] : $month = date("m"));
    if ((isset($_GET['y'])) ? $year = $_GET['y'] : $year = date("Y"));
    # Create arrays for the calendar
    $months_days = array("31","28","31","30","31","30","31","31", "30","31","30","31");
    $months_name = array("Jan","Feb","Mar","Apr","May","Jun","Jul", "Aug","Sep","Oct","Nov","Dec");
    $days_array = array("Mon","Tue","Wed","Thu","Fri","Sat","Sun");
    # Removes the 0 from start of month (can't find array key with 0)
    if (strlen($month) == 1) {
      $month = str_replace("0","",$month);
    } else {
      $month = $month;
    }
    # Reset month to the array key match (array starts at 0)
    $month = $month-1;
    # Find the days in the month
    $days_in_month = $months_days[$month];
    # And convert the month number to name
    $month_name = $months_name[$month];
    # $m is used to find month
    $m = $month+1;
    # Find the first day of the month
    $time = date("M D Y H:i:s", mktime(0, 0, 0, $m, 1, $year));
    $first_day = explode(" ",$time);
    $time = $first_day[1];
    ##### Create the links to next and previous months
    $next = $month+2;
    $x = $year;
    # If month is 13 then new year
    if ($next == 13) {
      $next = 1;
      $x = $x+1;

给你的三个提示

if ($value == $time) { $new_time .= $key+1; } else { $new_time .= ""; } 可以写成 if ($value == $time) { $new_time .= $key+1; } 因为 .= "" 不会更改字符串。

if (($year % 4 == "") && ($month == 1)) { $days_in_month = $days_in_month+1; } else { $days_in_month = $days_in_month; } 可以写成 if (!($year % 4) && $month === 1) { $days_in_month++; } 因为 $days_in_month = $days_in_month; 不会改变你的变量。

并填补最后 5 天不活跃；你有一个变量 $k 并且你知道每行有 7 天（列）。完成当前月份后，您需要继续循环以吐出不活动的 div，直到 !(($k+1) % 7) 或类似。行的第一个结尾意味着漂亮的方框的结尾。

未经测试且不受喜爱的代码：

for ($k = 1; $k < ($days_in_month+$new_time) || (($k-1) % 7); $k++) { if ($k < $new_time || $k >= ($days_in_month+$new_time)) { $calendar .= ' <div class="inactive"></div>' . "\n"; continue; } # Start the actual days $n = $k-$new_time+1; if ($n == $day) { $calendar .= ' <div class="today">' . $n . '</div>' . "\n"; } else { $calendar .= ' <div class="day">' . $n . '</div>' . "\n"; } }
