大家好，我有一个问题向大家请教。我们公司的网站是用PHP开发的，现在我们需要更改页面的布局，但是用DREAMWEAVER2004MX打开PHP代码后，在设计栏只看到几个字符，图片、布局都不显示，咋回事？代码如下：
<?
if(!session_is_registered("user_session"))
{
session_start(); //session_start()要写在首页的第一行，因为在他之前不能有任何html标记，否则PHP提示出错。
}
?>
<?
include("./manager/dbclass.php");
$dbobj=new DBclass;
$dbobj->connect();
function Gettime($JKLDate)
{ $date_array = explode("-",$JKLDate);
$var_year = $date_array[0];
$var_month = $date_array[1];
$var_day = $date_array[2];
$var_time = mktime(0,0,0,$var_month,$var_day,$var_year);
return($var_time);
}
function ConvertTime($strTime)
{
$strCovertTime = trim($strTime);
$strCovertTime = substr($strCovertTime,0,4)."-".substr($strCovertTime,4,2)."-".substr($strCovertTime,6,2);
return($strCovertTime);
}
function ConvertType($strType)
{
$strCovertType = trim($strType);
$strCovertType = substr($strCovertType,0,4)."交易";
return($strCovertType);
}
function ConvertTime1($strTime)
{
$strCovertTime = trim($strTime);
$strCovertTime = substr($strCovertTime,0,4)."-".substr($strCovertTime,5,2)."-".substr($strCovertTime,8,2);
return($strCovertTime);
}
?>
