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');
zip and download files using php
Thanks for your answers.
<?php
$files = array('Dear GP.docx','ecommerce.doc');
# create new zip opbject
$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
$zip->close();
# send the file to the browser as a download
header('Content-disposition: attachment; filename=Resumes.zip');
header('Content-type: application/zip');
readfile($tmp_file);
?>
Download multiple files as a zip-file using php
You can use the ZipArchive class to create a ZIP file and stream 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);
}
$zip->close();
and to stream it:
header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);
The second line forces the browser to present a download box to the user and prompts the name filename.zip. The third line is optional but certain (mainly older) browsers have issues in certain cases without the content size being specified.

Creating zip of multiple files and download in laravel
Only pure php code.
public function makeZipWithFiles(string $zipPathAndName, array $filesAndPaths): void {
$zip = new ZipArchive();
$tempFile = tmpfile();
$tempFileUri = stream_get_meta_data($tempFile)['uri'];

return;
}
// Add File in ZipArchive
foreach($filesAndPaths as $file)

}
}
// Close ZipArchive
$zip->close();

rename($tempFileUri, $zipPathAndName);
}
How to create a ZIP file using PHP and delete it after user downloads it?
Well, you'll have to first create the zipfile, using the ZipArchive class.
Then, send :
- The right headers, indicating to the browser it should download something as a zip -- see
header()-- there is an example on that manual's page that should help - The content of the zip file, using
readfile()
And, finally, delete the zip file from your server, using unlink().
Note : as a security precaution, it might be wise to have a PHP script running automatically (by crontab, typically), that would delete the old zip files in your temporary directory.
This just in case your normal PHP script is, sometimes, interrupted, and doesn't delete the temporary file.
create and download zip file using php
Why not use the Zip Encoding Class in Codeigniter - it will do this for you
$name = 'mydata1.txt';
$data = 'A Data String!';
$this->zip->add_data($name, $data);
// Write the zip file to a folder on your server. Name it "my_backup.zip"
$this->zip->archive('/path/to/directory/my_backup.zip');
// Download the file to your desktop. Name it "my_backup.zip"
$this->zip->download('my_backup.zip');

How to create a zip file and download it?
Within the line
ZipEntry anEntry = new ZipEntry(f.getPath());
you specify the path inside your zip file (i.e. f.getPath()). If you want a shorter path or none at all just manipulate this part (e.g. f.getName()).
