上传Zip文件并解压缩Zip

我有一个表单(HTML),它将文件提交给PHP脚本,该脚本将文件重命名为ZIP,将其存储在一个文件夹(随机名称)中,然后提取该文件.

文件上传.文件夹已正确创建.该文件被正确重命名.

拉链的提取失败.

这是我的表格:



Select file

这是PHP脚本 - up.php

$file_name = $HTTP_POST_FILES['ufile']['name'];
$random_digit=rand(0000,9999);
$new_file_name=$random_digit.".zip";
mkdir($random_digit, 0777, true);

$path= $random_digit.'/'.$new_file_name;
if($ufile !=none)
 {
    if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path))
 {
 echo "The upload is successful
"; 
 echo "File Renamed to: ".$new_file_name." for processing.
"; 
 echo "File Size :".$HTTP_POST_FILES['ufile']['size']."
"; 
 echo "Proceed to the next phase of the importation of data to the system
";
  }
 else
  {
   echo "Error";
   }
 }

  $zip = new ZipArchive;
  $res = $zip->open($new_file_name);
  if ($res === TRUE) {
     $zip->extractTo($random_digit.'/');
     $zip->close();
     echo 'extraction successful';
     } else {
     echo 'extraction error';
     }

它是防止提取的文件夹的模式吗？据我所见,没有语法错误.
