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>

  <tr>

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