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>

<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”WILL什么意思;)

{

$content = file($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体育格言-1];

}

you的复数形式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徐良的歌词>”;

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]));

}

}

fclo($fp);

echo &#拜新年凤凰传奇8220;<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>

<input type=ret value=重写 name=ret>

</td>

</form>

<?include(‘bottom.htm’);?>
