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');

if ($password!=$managepwd and $dispflag)

{

echo "<p>程序将在3秒返回</p>";

exit;

$text="";

for ($h=$count;$h>0;$h--)

{

$text=$text.$content[$h-1];

}

echo "$text";

}

$guest_content=file($guestfile);

$guest_content[$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 "<br>";

echo "</center>";

exit;

}

}

?>

<tr>
