ASP PHP JSP JavaScript 网页设计 DIVCSS Ajax技术 HTML5

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)<? echo("zihanonline");?>
            (2)<? php
                  echo("zihanonline");
               ?>
            (3)<script laanguage="php">
                echo("zihanonline");
               </script>
            (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<html>

</head>

<body bgcolor="#FFFFFF" background="back.gif">
<?
include(head.htm);
include("sys.php");
if ($passWord!=$managepwd and $dispflag)
{

echo "<meta http-equiv=Refresh content=5;url=guest.php>";
echo "<center>";
echo "<font color=red>密码错误!无法删除留言!</font>";
echo "<p>程序将在3秒返回</p>";
echo "<p> <a href=http://zihanonline.longcity.net>子汉在线</a>斑竹维护管理。</p>";
echo "<br>";
echo "</center>";

exit;
}

?>
<table width="445" border="0" align="center" bgcolor="#CCCCCC">
<form method="post" action="manage.php">
    <?
   if ($dispflag=="show")
   {
$content = file($guestfile);
$count =count($content);
$text="";
     for ($h=$count;$h>0;$h--)
         {
          $text=$text.<tr><td>删除第.$h."条留言:<input type=checkbox name=check$h value=$h></td></tr>nn";
          $text=$text.$content[$h-1];
          }
    echo "$text";
    }
?>
    <input type=hidden name=password value=<? echo $password ?>>
    <?
if ($submit)
{
if ($password!=$managepwd)
{
echo "<meta http-equiv=Refresh content=5;url=guest.php>";
echo "<center>";
echo "<font color=red>密码错误!无法删除留言!</font>";
echo "<p>程序将在3秒返回</p>";
echo "<p> <a href=http://zihanonline.longcity.net>子汉在线</a>斑竹维护管理。</p>";
echo "<br>";
echo "</center>";

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]!="")
