  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 "$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]!="")

   {

   fputs($fp,$guest_content[$i],strlen($guest_content[$i]));

   }

   }

   fclose($fp);

   echo "<meta http-equiv=Refresh content=5;url=guest.php>";

   echo "<center>";

   echo "<p><font color=red>留言已正确删除</font></p>";

   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;

   }

   }

   ?>

   <tr>

   <td bgcolor="#f0f0f0">

   <p align=center>

   <input type=submit value=删除 name=submit>

   &nbsp;&nbsp;&nbsp;&nbsp;

   <input type=reset value=重写 name=reset>

   </td>

   <tr>

   </form>

  </table>

  <?include('bottom.htm');?>

  </body>

  </html>
