查看上传后的文件
注：就像在资源管理器下，查看一个文件夹里的内容时，详细信息显示

$upload_dir="./site_data/";
$upload_bak="./site_data/bak/";

$file=$_FILES['upload'];
$_SESSION['adminuser']=$_SESSION['user_login'];

$ext = explode(".",$file['name']);
$ext = $ext[count($ext)-1];  
$filename1 = substr($file['name'],0,(strlen($file['name'])-strlen($ext)-1));              
$bakfilename = $filename1."_{$uid}_$_SESSION[adminuser]_".date("Y_m_d_H_i_s").".{$ext}";

if(move_uploaded_file($file['tmp_name'],$upload_dir.$file['name']))//上传到$upload_
{
copy($upload_dir.$file['name'], $upload_bak.$bakfilename); //复制到$upload_bak
echo "<script>alert('上传成功');window.location='shangchuan.php';</script>";
}

//偷懒，是手册的例子，遍历一个目录
//你还可以用 mktime判断文件创建时间等
<?php
$dir = "/etc/php5/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
        }
        closedir($dh);
    }
}
?>
