php簡單的檔案管理（下載檢視開啟目錄）
<?php
$down='file_dowm.php';
$path='./';
$url=$_SERVER['REQUEST_URI'];//訪問此頁面所需的 URI
if (isset($_GET['dir'])) {//判斷是否存在目錄
$path=$path.$_GET['dir'].'/';
}else{
$url=$url.'?dir=';
}
$fh=opendir($path);
$data=array();
while (($row=readdir($fh))!==false) {
if ($row=='.' || $row=='..') {
continue;
}
$row=iconv("gb2312", "utf-8",$row);
$data[]=$row;
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<table border="1">
<tr>
<td>檔名</td>
<td>操作</td>
</tr>
<?php foreach ($data as $v) { ?>
<tr>
<td><?php echo $v; ?></td>
<td>
<?php if(is_dir($path.$v)){ ?>
<a href="<?php echo $url.'/'.$v; ?>">開啟</a>
<a href="<?php echo $down.'?'.'id1'.'='.$v ?>">下載</a>
<?php }else{ ?>
<a href="<?php echo $path.$v; ?>">檢視</a>
<a href="<?php echo $down.'?'.'id1'.'='.$v ?>">下載</a>
<?php } ?>
</td>
</tr>
<?php } ?>
</table>
</body>
</html>
另外一個file_dowm.php檔案程式碼：
<?php
$one=$_GET['id1'];
$one=iconv("gb2312", "utf-8",$one);
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=".$one);
readfile($one);
?>
