Upload multiple files as a zip file using php

Question

How to upload multiple files as a zip file using php?

Answer 1

You can use the ZipArchive class to create a ZIP file and pass it to the client. Something like:

 $files = array('readme.txt', 'test.html', 'image.gif'); $zipname = 'file.zip'; $zip = new ZipArchive; $zip->open($zipname, ZipArchive::CREATE); foreach ($files as $file) { $zip->addFile($file); } $zip->close(); 

and pass it:

 header('Content-Type: application/zip'); header('Content-disposition: attachment; filename='.$zipname); header('Content-Length: ' . filesize($zipname)); readfile($zipname); 

The second line causes the browser to display the download window to the user and asks for the name filename.zip. The third line is optional, but some (mostly old) browsers have problems in certain cases without specifying the size of the content.

Answer 2

This is a working example of creating ZIP files in PHP:

 $zip = new ZipArchive(); $zip_name = time().".zip"; // Zip name $zip->open($zip_name, ZipArchive::CREATE); foreach ($files as $file) { echo $path = "uploadpdf/".$file; if(file_exists($path)){ $zip->addFromString(basename($path), file_get_contents($path)); } else{ echo"file does not exist"; } } $zip->close(); 

Answer 3

You can use the xip.lib.php library. zip.lib.php For example, see this article article

Answer 5

Are you ready to work with php zip lib, and can also use zend zip lib,

 <?PHP // create object $zip = new ZipArchive(); // open archive if ($zip->open('app-0.09.zip') !== TRUE) { die ("Could not open archive"); } // get number of files in archive $numFiles = $zip->numFiles; // iterate over file list // print details of each file for ($x=0; $x<$numFiles; $x++) { $file = $zip->statIndex($x); printf("%s (%d bytes)", $file['name'], $file['size']); print " "; } // close archive $zip->close(); ?>
