我有一个表单(HTML)，它向PHP脚本提交文件，PHP脚本将文件重命名为ZIP，将其存储在文件夹(随机名称)中，然后提取该文件。

文件将上载。文件夹已正确创建。文件被正确地重命名。

压缩包解压失败。

这是我的表格：

<form action="up.php" method="post" enctype="multipart/form-data" name="form1" id="form1">

Select file 
<input name="ufile" type="file" id="ufile" size="50" />

<input type="submit" name="Submit" value="Upload" />

 </form>

下面是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'], $path))
 {
 echo "The upload is successful<BR/>"; 
 echo "File Renamed to: ".$new_file_name." for processing.<BR/>"; 
 echo "File Size :".$HTTP_POST_FILES['ufile']['size']."<BR/>"; 
 echo "<strong><a style='color:#6A8DBC; text-decoration:none' href='".$link_address."'>Proceed to the next phase of the importation of data to the system</a></strong></br>";
  }
 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';
     }

是文件夹的模式阻止了解压缩吗？据我所知，没有语法错误。

file-upload

zip

extract

php

试一试

$res = $zip->open($path)

由于您已将文件移动到$path，因此需要在$path中对该文件进行操作
