public function downloadposts(int $id)
{
$post = Post::find($id);
// Define Dir Folder
$public_dir = public_path() . DIRECTORY_SEPARATOR . 'uploads/post/zip';
$file_path = public_path() . DIRECTORY_SEPARATOR . 'uploads/post';
// Zip File Name
$zipFileName = $post->post_title . '.zip';
// Create ZipArchive Obj
$zip = new ZipArchive();
if ($zip->open($public_dir . DIRECTORY_SEPARATOR . $zipFileName, ZipArchive::CREATE) === TRUE) {
// Add File in ZipArchive
foreach ($post->PostDetails as $postdetails) {
$zip->addFile($file_path, $postdetails->file_name);
}
// Close ZipArchive
$zip->close();
}
// Set Header
$headers = [
'Content-Type' => 'application/octet-stream',
];
$filetopath = $public_dir . '/' . $zipFileName;
dd($filetopath);
// Create Download Response
if (file_exists($filetopath)) {
return response()->download($filetopath, $zipFileName, $headers);
}
return redirect()->back();

尝试以下代码来创建多个文件的 zip：

{
$headers = ["Content-Type"=>"application/zip"];
$fileName = $id.".zip"; // name of zip
Zipper::make(public_path('/documents/'.$id.'.zip')) //file path for zip file
->add(public_path()."/documents/".$id.'/')->close(); //files to be zipped
return response()
->download(public_path('/documents/'.$fileName),$fileName, $headers);
}

Only pure php code.
只有纯php代码。
public function makeZipWithFiles(string $zipPathAndName, array $filesAndPaths): void
{
$zip = new ZipArchive();
$tempFile = tmpfile();
$tempFileUri = stream_get_meta_data($tempFile)['uri'];
if ($zip->open($tempFileUri, ZipArchive::CREATE) === TRUE) {
// Add File in ZipArchive
foreach($filesAndPaths as $file)
{
if (! $zip->addFile($file, basename($file))) {
echo 'Could not add file to ZIP: ' . $file;
}
}
// Close ZipArchive
$zip->close();
} else {
echo 'Could not open ZIP file.';
}
echo 'Path:' . $zipPathAndName;
rename($tempFileUri, $zipPathAndName);
}
