php做的上传工具~~必须先配置好文件~用的是XML

<?php
$file=$_GET["file_name"];
//echo $file;
$file_name = $file; 
$file_dir = "/AppServ/www/source/upload_file/"; 
if (!file_exists($file_dir.$file_name)) 
{ 
  echo "文件找不到"; 
  exit; 

} 
else 
{ 
$file = fopen($file_dir.$file_name,"r"); 
Header("Content-type: application/octet-stream"); 
Header("Accept-Ranges: bytes"); 
Header("Accept-Length: ".filesize($file_dir.$file_name)); 
Header("Content-Disposition: attachment; filename=".$file_name); 
echo fread($file,filesize($file_dir.$file_name)); 
fclose($file); 
exit;
