上两节我针对guest.php和edit.php作了讲述.需要注意的是php和html的区别:
php通常是-->(1)
            (2) echo("zihanonline");
?>
            (3)
            (4)<% echo("zihanonline");%>
等4种方式.不要混淆.
下面我们来研究信息管理:manage.php代码.
-----------
//manage.php

留言管理

include(head.htm);
include("sys.php");
if ($passWord!=$managepwd and $dispflag)
{

echo "";
echo "

";
echo "密码错误!无法删除留言!";
echo "

程序将在3秒返回

";
echo "

";
echo "
";
echo "";

exit;
}

    if ($dispflag=="show")
{
$content = file($guestfile);
$count =count($content);
$text="";
for ($h=$count;$h>0;$h--)
         {
          $text=$text.nn";
          $text=$text.$content[$h-1];
          }
    echo "$text";
    }
?>
    >
    if ($submit)
{
if ($password!=$managepwd)
{
echo "";
echo "";
echo "密码错误!无法删除留言!";
echo "

程序将在3秒返回

";
echo "

echo "

echo "";

exit;
}

if ($password==$managepwd)
{
$guest_content=file($guestfile);
$count=count($guest_content);
for ($j=1;$j<=$count;$j++)
{
$del_rec_num="check".$j;
$del_num=$$del_rec_num;
//echo "$del_num:$del_num";
$guest_content[$del_num-1]="";
}

$fp=fopen($guestfile,"w");
for ($i=0;$i<=$count-1;$i++)
{
if ($guest_content[$i]!="")
   {
   fputs($fp,$guest_content[$i],strlen($guest_content[$i]));
   }
}
fclose($fp);
echo "";
echo "

echo "
