需要帮助，请堆叠器。在一定程度上起作用，但陷入中圈并超时。显示所选月份的日期，我需要检入数据库并用不同的类突出显示有数据的日期。
我知道有一些类似的脚本，但这是响应性的，在sqlite上运行，不使用表。
这就是我得到的：
#############################################################
$months31 = array("01","03","05","07","08","10","12"); // MONTHS WITH 31 DAYS
if($_SESSION['m'] == 02): // IF FEBRUARY
$daysinmonth = cal_days_in_month (CAL_GREGORIAN , $_SESSION['m'] , $_SESSION['y']); // CHECK DAYS IN FEBRUARY AND CHECK FOR LEAP YEAR
elseif(in_array($_SESSION['m'],$months31 )): // IF IN ARRAY OF MONTHS WITH 31 DAYS
$daysinmonth = 31; // DAYS IN MONTH = 31
else:
$daysinmonth = 30; // DAYS IN MONTH = 30
endif;
########## ADD DAYS OF SELECTED MONTH ############
$d = 1;
$day = $d ;
$selectedmonth = $_SESSION['m'];
$selectedyear = $_SESSION['y'];
##################################################
while($d <= $daysinmonth):
####################### GET DATA FROM DATABASE FOR SELECTED YEAR AND MONTH #################
$calshow = $caldb->query("SELECT day FROM calandar WHERE month = '$selectedmonth' AND year = '$selectedyear' ");
foreach($calshow as $cal):
$showday = $cal['day'];
############ HIGHLIGHTS CURRENT DAY ############
if($d == $curday && $_SESSION['m']== $curmonth && $_SESSION['y'] == $curyear):
$today = 'sel';
else:
$today = '';
endif; ?>
<a href="####">
<li class="day <?php echo $today;?><?php if($showday == $d): echo 'data'; endif;?>"><?php echo $d++;?></li></a>
<?php endforeach;
endwhile;?>
这是您的问题：
while($d <= $daysinmonth):
您没有在循环中增加$d，因此它永远不会结束。除此之外，我也不知道你在哪里设置了$daysinmonth。
你可能想这样结束你的循环：
$d++;
endwhile;?>
或者您可能需要在foreach()循环中重置并增加$d。
Hurrah排序！！！在数据库中创建一个时间戳为y-m-d的行，然后进行行计数用于当月带有日期戳的记录由于我使用的是SQLITE和PDO，我需要使用$rows=$calshow->fetchAll（）；并使用count（$rows）进行查询！=0-知道如何操作时很简单；-）
此处为工作脚本http://i3ry.com/cal/如果它对任何有同样问题的人有用（有充分记录）
$day = $d ;

while($d <= $daysinmonth):
$selectedmonth = $_SESSION['m'];
$selectedyear = $_SESSION['y'];
$datestamp = $selectedyear.'-'.$selectedmonth.'-'.$d;
### check if there are appointments ###
$calshow = $caldb->query("SELECT datestamp FROM calandar WHERE datestamp = '$datestamp' AND month = '$selectedmonth' AND year = '$selectedyear'");
$rows = $calshow ->fetchAll(); // COUNT ROWS WHICH MATCH DATESTAMP QUERY
