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>
<title>留言管理</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<style>
<!--
A:link {text-decoration: none ; color:0000ff}
A:visited {text-decoration: none; color:004080}
A:active {text-decoration: none}
A:hover {text-decoration: underline; color:ff0000}
BODY {FONT-SIZE: 9p}
TH {FONT-SIZE: 9pt}
TD {FONT-SIZE: 9pt}
-->
</style>

</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 "$
