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">
