How to create zip file and download using PHP ZipArchive?

During the project development process, we may need to implement the function of creating zip files and providing downloading. So here we can use the ZipArchive class to create a zip file and then download it.

Let me give you a simple example. Sometimes we need to use php code to create a zip archive file, add some photos, documents, etc. to the zip file, and then provide it for download. Here we will create a very simple method createZip() which will help create zip archive files. Using this method, you can simply pass an array of files, documents, images and paths.

Below I wrote a very simple index.php file example , you can copy it directly and run it locally for testing.

Make sure there is an available image file in the index.php file:

1）demo1.jpg 2）demo2.jpg

The code example is as follows:

open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) { return false; } foreach($validFiles as $file) { $zip->addFile($file,$file); } $zip->close(); return file_exists($destination); }else{ return false; } } $fileName = 'my-archive.zip'; $files_to_zip = ['demo1.jpg', 'demo2.jpg']; $result = createZip($files_to_zip, $fileName); header("Content-Disposition: attachment; filename=\"".$fileName."\""); header("Content-Length: ".filesize($fileName)); readfile($fileName);
