Download the zip file and extract the zip file

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

The file is loading. The folder is created correctly. The file will be renamed correctly.

Zip extraction fails.

Here is my form:

<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 a PHP script - 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 this folder mode that prevents extraction? As far as I can see, there is no syntax error.

to try

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

When you moved the file to $path , you will need to work with the file in $path
