$tmpname = $_FILES['upfile']['tmp_name']; // 临时文件名称
$name = $_FILES['upfile']['name']; // 文件的原名称
$path = './uploads/'.$xm.'_'.$xh;// 上传目录
$file_name = date('YmdHis').rand(100,999)."_".$name;// 避免文件重名，更改文件名称
if(!file_exists($path)){

}
if(move_uploaded_file($tmpname, $path.'/'.$file_name)){
echo $name." 上传成功！<br>";

5、showFile.php 结果显示页
<?php
if(!isset($_GET['xm']) || empty($_GET['xm'])){
echo "参数错误！";
return;
}
if(!isset($_GET['xh']) || empty($_GET['xh'])){

$file_name = $xm.'_'.$xh;
$path = ".".DIRECTORY_SEPARATOR."uploads".DIRECTORY_SEPARATOR.$file_name;
if(!file_exists($path)){
echo "未找到文件目录";
return;
}
function readAllFileFromDir($dir, $level = 0)
{

6、download.php 文件下载处理页
<?php
if(!isset($_GET['file_name']) || empty($_GET['file_name'])){
echo "参数错误！";
return;
}
$file_name = trim($_GET['file_name']);
$path = "./uploads/".$file_name;
if(!file_exists($path)){
echo "未找到文件";
return;
}
//增加路径验证
if(strpos(realpath($path), realpath("./uploads")) !== 0){
echo "路径错误:". dirname($path);
return;
}
$file_Size = filesize($path);
$downname = str_replace('_', '', mb_strstr(basename($file_name), '_'));
header("Content-type:application/octet-stream");
header("Accept-Ranges:bytes");
header("Accept-Length:".$file_Size);
header("Content-Disposition: attachment; filename=".$downname);
readfile($path);
