Create Zip compressed files in Laravel and provide downloads

If you need your users to support multiple file downloads, the best way is to create a zip file and provide it for download. Take a look at the implementation in Laravel.

In fact, this is not about Laravel, but more about PHP. We are going to use the ZipArchive class that has existed since PHP 5.2, and if we want to use it, we need to make sure that the ext-zip extension in php.ini is turned on.

Task 1: store the user's invoice file to storage/invoices/aaa001.pdf

The following is a code demonstration:

$zip_file = 'invoices.zip'; / / name of the compressed package to be downloaded / / initialize the PHP class $zip = new\ ZipArchive (); $zip- > open ($zip_file,\ ZipArchive::CREATE |\ ZipArchive::OVERWRITE); $invoice_file =' invoices/aaa001.pdf' / / add a file: the second parameter is the path of the file to be compressed in the package / / so it will create another path called "storage/" in ZIP and put the file in the directory. $zip- > addFile (storage_path ($invoice_file), $invoice_file); $zip- > close (); / / We will return the file as it is immediately after downloading the file, return response ()-> download ($zip_file)

The example is simple, isn't it?

Task 2: compress all files into the storage/invoices directory

There is no need to change anything in the Laravel aspect, we just need to add some simple PHP code to iterate over these files.

$zip_file = 'invoices.zip';$zip = new\ ZipArchive (); $zip- > open ($zip_file,\ ZipArchive::CREATE |\ ZipArchive::OVERWRITE); $path = storage_path (' invoices'); $files = new\ RecursiveIteratorIterator (new\ RecursiveDirectoryIterator ($path)); foreach ($files as $name = > $file) {/ / We want to skip all subdirectories if (! $file- > isDir ()) {$filePath = $file- > getRealPath () / / get the file extension $relativePath = 'invoices/'. Substr ($filePath, strlen ($path) + 1); $zip- > addFile ($filePath, $relativePath);}} $zip- > close (); return response ()-> download ($zip_file)

It's almost done here. You see, you don't need any Laravel extension packs to implement this compression.
