可让软件读取更新的PHP页面

如果直接访问页面,会显示公开信息. 带p值访问,会显示隐藏信息.
不是什么新异的思路,刚才写个小软件需要用到自动更新,所以就写了这个PHP来让软件读取.
index.php是主页面,
up.php是上传附件页面,呃.这个页面貌似没什么用

1. [PHP]代码

index.php
 
<?php
//Y-m-d H:i:s任选 分别是取年月日时分秒
$n1="azhus.com".date("H"); //第一个权限
$n2="azhus".date("H"); //第二个权限
 
$p=$_POST[&#39;p&#39;]; //p为POST的p参数
 
 
if ($p==$n1)
  echo "版本:2;地址:http://bbs.vvell.com/201304/13175552.rar;"; //格式为"版本:**;地址:**;" 下同
elseif ($p==$n2)
  echo "版本:3;地址:http://bbs.vvell.com/201304/13175628.rar;"; 
else
  echo "公告:<br>来自爱注释论坛,http://azhus.com"; 
 
?>
 
 
up.php
 
<?
    $fileup     = 0; //上传功能开关 0打开 1关闭
    $filesize   = 200; //文件大小单位KB 1M=1024KB
    $filetype   = array(&#39;jpg&#39;,&#39;gif&#39;,&#39;bmp&#39;,&#39;rar&#39;,&#39;zip&#39;,&#39;7z&#39;); //文件类型
    $filepath   = &#39;./&#39;; //文件保存目录 后面要加/ 不能超过两级目录
if ($_GET[&#39;up&#39;]){
    if ($fileup) exit (&#39;上传功能已关闭！&#39;);
    $fileend = end(explode(&#39;.&#39;,basename($_FILES[&#39;file&#39;][&#39;name&#39;])));//取得后缀名
    //判断文件类型和大小
    if(in_array($fileend,$filetype) && $_FILES[&#39;file&#39;][&#39;size&#39;] < 1024*$filesize){
        if (!file_exists($filepath)) mkdir ($filepath);
        //如果不是当前目录需要这句 判断文件保存目录是否存在 没有则创建
        $filepath = $filepath.date(&#39;Ym&#39;).&#39;/&#39;;//以年月作为目录
        if (!file_exists($filepath)) mkdir ($filepath);//判断年月目录是否存在 没有则创建
        date_default_timezone_set(&#39;PRC&#39;);//中国时间
        $fileurl = $filepath.date(&#39;dHis.&#39;).$fileend;//文件路径 用日时分秒作为文件名
        move_uploaded_file($_FILES[&#39;file&#39;][&#39;tmp_name&#39;],$fileurl);//把上传的文件移动到我们指定的文件路径
    }else{
        exit(&#39;<script>alert("文件大小或类型错误！");location="?";</script>&#39;);
    }
}
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>上传文件</title>
</head>
<body style="font-size:14px; line-height:25px;">
<? if($_GET[&#39;up&#39;]){ ?>
    <p>
    <strong>上传成功!</strong><br/>请复制文件地址：
    <input type="text" onClick="select();" value="<? if ($_GET[&#39;up&#39;]) echo $fileurl ?>" /><br/>
    点文本框自动全选 Ctrl+C 复制 或 鼠标右键复制<br/>
    在需要使用的地方 Ctrl+V 粘贴 或 鼠标右键粘贴
    </p>
<? }?>
<? if($fileend==&#39;jpg&#39;||$fileend==&#39;gif&#39;||$fileend==&#39;bmp&#39;){ ?>
    <p><strong>图片预览</strong>：<br>
    <img src="<?=$fileurl?>"/></a></p>
<? }?>
<form method="post" action="?up=file" enctype="multipart/form-data">
    <input name="file" type="file"><input type="submit" value="上传">
</form>
<p><strong>大小：</strong><?=$filesize?> KB<br/><strong>类型：</strong>
<? for($i=0; $i < count($filetype); $i++) echo $filetype[$i],&#39; &#39; ?></p>
</body>
</html>
