PHP文件助手 - 源代码

实现效果

lqlsyor5.png

PHP文件上传+下载代码

缺点:
BUG一堆,,没有做文件任何验证检测等,可以直接上传到文件夹

说明:

  1. 源代码来源于互联网
  2. 文件上传默认目录:file/userFile下
  3. 下载必须使用全名(要带后缀名),且上传的文件必须全英文,不可出现汉字

index.html

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

upload.php

<?php
 
    header("Content_type:text/html;charset=utf8");
    
    //session_start();
    
    $imgname = $_FILES['myFile']['name'];
    $tmp = $_FILES['myFile']['tmp_name'];
    $error=$_FILES['myFile']['error'];
        
   move_uploaded_file($tmp,'file/userFile/'.iconv("UTF-8", "gbk",$imgname));
 
   if ($error==0) {
              echo "上传成功!";
   }else{
          switch ($error){
            case 1:
              echo "超过了上传文件的最大值,请上传500M以下文件";
              break;
            case 2:
              echo "上传文件过多,请一次上传20个及以下文件!";
              break;
            case 3:
              echo "文件并未完全上传,请再次尝试!";
              break;
            case 4:
              echo "未选择上传文件!";
              break;
            case 5:
              echo "上传文件为0";
               break;
    }
}
 
?>

download.php

<?php

    header("Content-Type:text/html;charset=utf8");
    
        $file_name = $_GET['filename'];
                
        $download_path = "file/userFile/";
 
        if(!file_exists($download_path.$file_name)){
            
        //Header("Content-type:text/html;charset=utf-8");
            
        echo "文件不存在!</br>";
        
        exit;
        
    }else{
                    
    $file=fopen($download_path.$file_name,"r");
        
    header('Content-Typr:application/octet-stream');
    
    header("Accept-Ranges: bytes");
    
    header("Content-Disposition:attachment;filename=".$file_name);
    
    header('Content-length:'.filesize($download_path.$file_name));
    
    readfile($download_path.$file_name);
    
}
?>

环境修改:

.ini文件设置:

  1. post_max_size = 501M
  2. max_file_uploads = 20
  3. post_max_size = 30M
