如果您明确告诉我们您希望此代码做什么以及它实际做什么，您更有可能获得帮助。您遇到了什么错误？此代码用于获取日期之间的出勤率。我希望从一个日期到另一个日期有2个textboxinput，当执行查询时，表会获取该日期之间数据库中的所有列，它显示没有记录。我知道从哪里获取$rows？您编写了一个sql语句，但没有执行它。先生，它仍然不起作用。除了：require_once'Connection.simple.php'$conn=dbConnect$OK=正确@akki2401尝试硬编码日期：$dateFrom='2014-01-01'，$dateTo='2014-12-31'以下是我一直在尝试的：&@akki2401问题出在哪里？@akki2401删除$sql中参数名称周围的引号：SELECT*FROM attentication WHERE date>=：date_FROM和date='：date_FROM'和date='
