Zip All Files in Directory and Download Generated .Zip

ZIP all files in directory and download generated .zip

this will ensure a file with .php extension will not be added:

   foreach ($files as $file) {
        if(!strstr($file,'.php')) $zip->addFile($file);
    }

edit: here's the full code rewritten:

<?php

    $zipname = 'adcs.zip';
    $zip = new ZipArchive;
    $zip->open($zipname, ZipArchive::CREATE);
    if ($handle = opendir('.')) {
      while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != ".." && !strstr($entry,'.php')) {
            $zip->addFile($entry);
        }
      }
      closedir($handle);
    }

    $zip->close();

    header('Content-Type: application/zip');
    header("Content-Disposition: attachment; filename='adcs.zip'");
    header('Content-Length: ' . filesize($zipname));
    header("Location: adcs.zip");

    ?>

ZIP all files and then download

Try this

 public string MergeFiles(string folder)
    {
        using (ZipFile zip = new ZipFile(folder))
        {
            string[] fileEntries = Directory.GetFiles(folder);
            foreach (string f in fileEntries)
            {
                string path = Path.GetDirectoryName(f.Substring(folder.Length));
                    zip.AddFile(f, path);
            }
            zip.Save(folder + "\\files.zip");
        }
        return folder+"\\files.zip";
    }

How to zip a whole folder using PHP

Code updated 2015/04/22.

Zip a whole folder:

// Get real path for our folder
$rootPath = realpath('folder-to-zip');

// Initialize archive object
$zip = new ZipArchive();
$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);

// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($rootPath),
    RecursiveIteratorIterator::LEAVES_ONLY
);

foreach ($files as $name => $file)
{
    // Skip directories (they would be added automatically)
    if (!$file->isDir())
    {
        // Get real and relative path for current file
        $filePath = $file->getRealPath();
        $relativePath = substr($filePath, strlen($rootPath) + 1);

        // Add current file to archive
        $zip->addFile($filePath, $relativePath);
    }
}

// Zip archive will be created only after closing object
$zip->close();

Zip a whole folder + delete all files except "important.txt":

// Get real path for our folder
$rootPath = realpath('folder-to-zip');

// Initialize archive object
$zip = new ZipArchive();
$zip->open('file.zip', ZipArchive::CREATE | ZipArchive::OVERWRITE);

// Initialize empty "delete list"
$filesToDelete = array();

// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($rootPath),
    RecursiveIteratorIterator::LEAVES_ONLY
);

foreach ($files as $name => $file)
{
    // Skip directories (they would be added automatically)
    if (!$file->isDir())
    {
        // Get real and relative path for current file
        $filePath = $file->getRealPath();
        $relativePath = substr($filePath, strlen($rootPath) + 1);

        // Add current file to archive
        $zip->addFile($filePath, $relativePath);

        // Add current file to "delete list"
        // delete it later cause ZipArchive create archive only after calling close function and ZipArchive lock files until archive created)
        if ($file->getFilename() != 'important.txt')
        {
            $filesToDelete[] = $filePath;
        }
    }
}

// Zip archive will be created only after closing object
$zip->close();

// Delete all files from "delete list"
foreach ($filesToDelete as $file)
{
    unlink($file);
}

How to create a zip archive of a directory?

As others have pointed out, you should use zipfile. The documentation tells you what functions are available, but doesn't really explain how you can use them to zip an entire directory. I think it's easiest to explain with some example code:

import os
import zipfile
    
def zipdir(path, ziph):
    # ziph is zipfile handle
    for root, dirs, files in os.walk(path):
        for file in files:
            ziph.write(os.path.join(root, file), 
                       os.path.relpath(os.path.join(root, file), 
                                       os.path.join(path, '..')))

with zipfile.ZipFile('Python.zip', 'w', zipfile.ZIP_DEFLATED) as zipf:
    zipdir('tmp/', zipf)

Dowloading a .zip directory with HttpHandler

You could just use WebClient for a 2-liner:

using(Webclient wc = new WebClient())
{ 
   wc.DownloadFile(url, @"D:\downloads\1.zip");
}

Need to ZIP an entire directory using Node.js

I ended up using archiver lib. Works great.

Example

var file_system = require('fs');
var archiver = require('archiver');

var output = file_system.createWriteStream('target.zip');
var archive = archiver('zip');

output.on('close', function () {
    console.log(archive.pointer() + ' total bytes');
    console.log('archiver has been finalized and the output file descriptor has closed.');
});

archive.on('error', function(err){
    throw err;
});

archive.pipe(output);

// append files from a sub-directory, putting its contents at the root of archive
archive.directory(source_dir, false);

// append files from a sub-directory and naming it `new-subdir` within the archive
archive.directory('subdir/', 'new-subdir');

archive.finalize();

Create zip file from all files in folder

Referencing System.IO.Compression and System.IO.Compression.FileSystem in your Project

using System.IO.Compression;

string startPath = @"c:\example\start";//folder to add
string zipPath = @"c:\example\result.zip";//URL for your ZIP file
ZipFile.CreateFromDirectory(startPath, zipPath, CompressionLevel.Fastest, true);
string extractPath = @"c:\example\extract";//path to extract
ZipFile.ExtractToDirectory(zipPath, extractPath);

To use files only, use:

//Creates a new, blank zip file to work with - the file will be
//finalized when the using statement completes
using (ZipArchive newFile = ZipFile.Open(zipName, ZipArchiveMode.Create))
{
    foreach (string file in Directory.GetFiles(myPath))
    {
        newFile.CreateEntryFromFile(file, System.IO.Path.GetFileName(file));
    }              
}

Create a zip file and download it

Add Content-length header describing size of zip file in bytes.

header("Content-type: application/zip"); 
header("Content-Disposition: attachment; filename=$archive_file_name");
header("Content-length: " . filesize($archive_file_name));
header("Pragma: no-cache"); 
header("Expires: 0"); 
readfile("$archive_file_name");

Also make sure that there is absolutely no white space before <? and after ?>. I see a space here:

↓

 <?php
$file_names = array('iMUST Operating Manual V1.3a.pdf','iMUST Product Information Sheet.pdf');
