Create zip with PHP adding files from url [closed]

Asked 18/12, 2012 at 9:38 Answered 18/12, 2012 at 9:53

I was wondering if the following is possible to do and with hope someone could potentially help me.

I would like to create a 'download zip' feature but when the individual clicks to download then the button fetches images from my external domain and then bundles them into a zip and then downloads it for them.

I have checked on how to do this and I can't find any good ways of grabbing the images and forcing them into a zip to download.

I was hoping someone could assist

You are describing quite a complex set of operations - you're question is not specific. What part of this are you having problems with? What have you tried? – Reitz 18/12, 2012 at 9:41

I was more curious if there is such a way to download images from external domain into a zip file. I'm currently researchign possibilities – Trephine 18/12, 2012 at 9:43

# define file array
$files = array(
    'https://www.google.com/images/logo.png',
    'https://en.wikipedia.org/static/images/project-logos/enwiki-2x.png',
);

# create new zip object
$zip = new ZipArchive();

# create a temp file & open it
$tmp_file = tempnam('.', '');
$zip->open($tmp_file, ZipArchive::CREATE);

# loop through each file
foreach ($files as $file) {
    # download file
    $download_file = file_get_contents($file);

    #add it to the zip
    $zip->addFromString(basename($file), $download_file);
}

# close zip
$zip->close();

# send the file to the browser as a download
header('Content-disposition: attachment; filename="my file.zip"');
header('Content-type: application/zip');
readfile($tmp_file);
unlink($tmp_file);

Note: This solution assumes you have allow_url_fopen enabled. Otherwise look into using cURL to download the file.

I receive the following "Windows cannot open the folder. The Compressed (zipped Folder 'C:\download.zip' is invalid – Trephine 18/12, 2012 at 10:8

@DonaldSutherland see my edit. I did some stupid stuff with variable names. – Lydia 18/12, 2012 at 10:23

Thanks for the code.. Anyway to also download folders/directories? – Prithee 11/4, 2014 at 14:44

@Mr_Green, you can't really do that unless directory listing is enabled on the server, and even then you'd have to parse the HTML to get all the files in each folder. – Lydia 13/4, 2014 at 2:23

@Lydia please have a look at this link. – Prithee 14/4, 2014 at 5:44

@Lydia thank you sir for the solution, but how do we clear the temp file after the download progress? – Grater 17/11, 2015 at 3:11

You should add unlink($tmp_file) after you read the file so it doesn't clutter up hosting space – Gauhati 16/12, 2016 at 15:55

thanks buddy. worked like a charm... – Pay 23/8, 2017 at 2:5

Zip is downloaded successfully but when I extract it thrown Archive is corrupted error. I have tried with the same example without any change. Still facing the same issue – Blastula 16/7, 2020 at 10:11

that's probably because http://google.com/images/logo.png no longer works. i've updated the examples to use https and fixed the 404 url. – Lydia 22/7, 2020 at 14:25

Error "Windows cannot open the folder. The Compressed (zipped Folder 'C:\download.zip' is invalid" still going on – Firedrake 18/8, 2022 at 14:13

probably because the wikipedia image no longer works - i've updated the example – Lydia 16/1, 2023 at 14:22

I hope I didn't understand wrong.

I haven't tried this, but it seems like what you're looking for.

<?php
$zip = new ZipArchive;

if ($zip->open('my_archive.zip') === TRUE) {
    $zip->addFile($url, basename($url));
    $zip->close();
    echo 'ok';
} else {
    echo 'failed';
}
?>
