【问题描述】：
我基本上是在创建一个日历，我想在其中显示学生的出勤率。如果学生是present 或absent，则计数器应分别增加到+1。但问题是，如果在某个地方没有记录日历日期的出勤率，则计数器无法增加present 或absent 的值。
这是代码：
$present_sids = explode(",",$a['present_sids']);
$absent_sids = explode(",",$a['absent_sids']);
$leave_sids = explode(",",$a['leave_sids']);
if ($a['att_date'] == "1")

{
$red_green_1 = '70ff7d';
$present_counter = '1';
}
elseif (in_array($sid,$absent_sids))
{
$red_green_1 = 'ff8b70';
$absent_counter = '1';
if (in_array($sid,$leave_sids))
{
$l_1 = ' (L)';
}
else
{
$l_1 = '';
}
}
}
if ($a['att_date'] == "2")
{
if (in_array($sid,$present_sids))
{
$red_green_2 = '70ff7d';
$present_counter = $present_counter+1;
}
elseif (in_array($sid,$absent_sids))
{
$red_green_2 = 'ff8b70';
$absent_counter = $absent_counter+1;
if (in_array($sid,$leave_sids))

$l_2 = ' (L)';

如您所见，礼物总数为 6，但礼物总数仅显示 4
请帮忙
【问题讨论】：
-
是 -
$a['present_sids']- 没有空格吗？ -
@Mr.Blue，它没有任何空白。也是的，那是一个计数器。
-
你可以试试 print_r($present_sids);显示输入。可能没有输入
-
确保
$a['att_date']也没有空格。 -
能否提供$a['present_sids']的字符串输入；这很容易调试，你的代码没有问题。输入可能有问题
