php 上传 Zip 文件并解压缩 Zip

Upload Zip File and Extract the Zip

提问by Cody Raspien

I have a form (HTML) which submits a file to a PHP script which renames the file to ZIP, stores it in a folder (random name) and then extracts that file.

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中（随机名称），然后提取该文件。

The file gets uploaded. The folder is created correctly. The file gets renamed correctly.

文件被上传。该文件夹已正确创建。文件被正确重命名。

The extraction of the zip fails.

zip 的提取失败。

Here is my form:

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>

Here is the PHP script - up.php

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'], $path))
 {
 echo "The upload is successful<BR/>"; 
 echo "File Renamed to: ".$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';
     }

Is it the mode of the folder which prevents extraction? As far as I can see, there is no syntax error.

是文件夹的模式阻止了提取吗？据我所知，没有语法错误。

try

尝试

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

As you have moved the file to $pathyou then need to operate on the file at $path

由于您已将文件移动到$path您，然后需要对文件进行操作$path
