php zip file - add new_ziparchive?

Question

I need to create a zzip file , i tried a script but i get an error message:

Warning: ZipArchive::addFile() [ziparchive.addfile]: Invalid or unitialized Zip object

this is my script:

<?php
$path = "./downloads/";

$file = $_FILES["file"]["name"];

$zip=new ZipArchive;

$zip->addFile('./downloads/', $_FILES["file"]["name"]); 
?>

Answer 1

Look at the example here .

You have to call the open method:

$zip->open("/path/to/filename.ext", ZIPARCHIVE::CREATE);

Or call the constructor in a different fashion:

$zip = new ZipArchive("/path/to/filename.ext", ZIPARCHIVE::CREATE);

Answer 2

您需要使用$_FILES["file"]["tmp_name"]而不是$_FILES["file"]["name"]
