否则更新类别回显显示图像
您好，
我需要在类别更新时显示图像，并且该图像最多显示 3 天
，我使用此但无法使用
$todaytime = time();
$timestamp = $show_wallpaper['timestamp'];
$timediffirence = "360000";
$minus = $todaytime - $timestamp;
if ($timediffirence > $minus) {
$new = "<img src='$siteurl/images/new.gif' />";
} else {
$new = "";
}
数据库信息
$sql = "SELECT SQL_NO_CACHE * FROM wallpaper WHERE categoryid = $catid order by wallpaperid desc LIMIT $from,$max_results";
，所以请帮助我修复它 我确实喜欢这个
IF 类别更新然后显示此图像 3 天，否则删除图像 这是我的任务 回复

首先，
$timediffirence是一个数字，因此不需要用双引号引起来，首先尝试一下：其次，360000不是3天以秒为单位，它应该是
((60 * 60) * 24) * 3 = 259200
最后，通过打印
$minus的值并将其与$时间差Firstly,
$timediffirenceis a number, it does not therefore need to be in double quotes, try this first:Secondly, 360000 is not 3 days in seconds, it should be
((60 * 60) * 24) * 3 = 259200
Finally, try debugging by printing out the values of
$minusand comparing it with$timediffirence
