这是我的代码：

<?php
function GetDays($sStartDate, $sEndDate){   
  $sStartDate = gmdate("Y-m-d", strtotime($sStartDate));   
  $sEndDate = gmdate("Y-m-d", strtotime($sEndDate));   

  $aDays[] = $sStartDate;   
  $sCurrentDate = $sStartDate;   
  while($sCurrentDate < $sEndDate){   
     $sCurrentDate = gmdate("Y-m-d", strtotime("+1 day", strtotime($sCurrentDate)));   
      $aDays[] = $sCurrentDate;   
  }   
    return $aDays;   
}  
?>

当我执行代码工作正常但是，数据不显示在同一页面中。 当数据显示时，页面正在刷新，因此我无法在同一页面中查看数据。

在开发应用，创建帐户并使用时，不应使用root用户名和密码，当您发布删除它时。

如果您的网页在加载后刷新，则问题必须来自您的JavaScript。 PHP是服务器端语言，这意味着它可以在用户输出之前重定向，但不能在之后重定向。将您的JS或链接发布到此处，以便我们提供更多帮助。

借调@ProNeticas - 从不在开发应用时使用root密码。

此外，您的代码向SQL injection开放 - 请阅读mysql_real_escape_string

@user ..我只是格式化您的代码......请查看并申请...然后我们将讨论您的问题......
