一代码

index.php

<html><head><title>文件浏览</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><style type="text/css"><!--a:link {text-decoration: none;}a:visited {text-decoration: none;}a:hover {text-decoration: none;}a:active {text-decoration: none;}.style1 {font-size: 12px}--></style></head><body><h3 align="center">文件浏览</h3>  <div align="center">    <table width="500" height="28" border="1" align="center" cellpadding="1" cellspacing="1" bordercolor="#FFFFFF" bgcolor="#999999">      <tr align="center" valign="middle" bgcolor="#A5F5BF" >        <th width="100" height="25" align="center" valign="middle" bgcolor="#FFFFFF"><span class="style1">项目名</span></th>        <th width="60" align="center" valign="middle" bgcolor="#FFFFFF"><span class="style1">大小</span></th>        <th width="150" align="center" valign="middle" bgcolor="#FFFFFF"><span class="style1">创建日期</span></th>        <th width="180" align="center" valign="middle" bgcolor="#FFFFFF"><span class="style1">最后修改时间</span></th>      </tr><?php     if(!isset($_GET[catalog])||empty($_GET[catalog]))$dqml=getcwd();//获得脚本目录        else $dqml=$_GET[catalog];    chdir($dqml);//改变当前目录        echo "当前目录:".getcwd()."<br>";    $ml = opendir($dqml);  //打开目录    while ($hqml = readdir($ml)){ //循环读取目录中的目录及文件    echo "<tr><td align='center' valign='middle' bgcolor='#FFFFFF'>";        if(is_dir($hqml)){  //判断是目录           if($hqml=="."){          $catalog=getcwd();//显示当前目录       echo "<a href=$php_self?catalog=$catalog><span class='style1'>锁定</span></a>"; }           elseif($hqml==".."){              $catalog=getcwd()."\\.."; //上级目录          echo "<a href=$php_self?catalog=$catalog><span class='style1'>上级目录</span></a>";           }else{          $catalog=getcwd()."\\$hqml";  //子目录          echo "<a href=$php_self?catalog=$catalog>$hqml</a>"; }    }else{            $ext=substr($hqml,strrpos($hqml,"."));if(strtoupper($ext)==".PHP"||strtoupper($ext)==".TXT"){    $catalog=getcwd();    echo "<a href=./indexs.php?catalog=$catalog&filename=$hqml&type=$ext>$hqml</a>"; }else{        echo "$hqml"; }  }    if(is_dir($hqml)) $file_size="目录";        else $file_size=round(filesize($hqml)/1024)."k";           echo "<td align='center' valign='middle' bgcolor='#FFFFFF'>$file_size</td>";        $create_time=date("y-m-d h:i:sA",filectime($hqml));           echo "<td align='center' valign='middle' bgcolor='#FFFFFF'>$create_time</td>";        $update_time=date("y-m-d h:i:sA",filemtime($hqml));           echo "<td align='center' valign='middle' bgcolor='#FFFFFF'>$update_time</td>"; }      closedir($ml); ?>    </table>  </div></body></html>

indexs.php

<html><head><title>文件浏览</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312"></head><body><a href="index.php">返回目录</a><br><?php    $catalog=$_GET[catalog];  //获取文件的信息   $filename=$_GET[filename];   $type=$_GET[type];//显示PHP文件的内容   if(strtoupper($type)==".php"){      readfile($catalog."\\".$filename);   }else{   //显示txt文件的内容      $fp=fopen($catalog."\\".$filename,"r");   while($line=fgets($fp)){      $line=htmlentities($line,ENT_COMPAT,"GB2312");      echo $line; }   fclose($fp); }  ?></body></html>
