Laravel 中创建 Zip 压缩文件并提供下载的实现方法

$zip_file = 'invoices.zip'; // 要下载的压缩包的名称
// 初始化 PHP 类
$zip = new \ZipArchive();
$zip->open($zip_file, \ZipArchive::CREATE | \ZipArchive::OVERWRITE);
$invoice_file = 'invoices/aaa001.pdf';
// 添加文件第二个参数是待压缩文件在压缩包中的路径
// 所以，它将在 ZIP 中创建另一个名为 "storage/" 的路径，并把文件放入目录。
$zip->addFile(storage_path($invoice_file), $invoice_file);
$zip->close();
// 我们将会在文件下载后立刻把文件返回原样
return response()->download($zip_file);

$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 => $file)
{
 // 我们要跳过所有子目录
 if (!$file->isDir()) {
  $filePath  = $file->getRealPath();

  // 用 substr/strlen 获取文件扩展名
  $relativePath = 'invoices/' . substr($filePath, strlen($path) + 1);

  $zip->addFile($filePath, $relativePath);
 }
}
$zip->close();
return response()->download($zip_file);
