php – 如何在laravel 5中压缩文件夹？

laravel zip文件需要一些帮助.我在公共文件夹中有一个文件夹,我想在用户单击按钮时创建该文件夹(temp_file文件夹)的zip.

public function testing()
{
    $public_dir = public_path('temp_file/');
    $zipFileName = 'myZip.zip';
    $zip = new ZipArchive;

    if ($zip->open($public_dir . '/' . $zipFileName, ZipArchive::CREATE) === TRUE) {
        $zip->addFile('file_path', 'file_name');
        $zip->close();
    }

    $headers = array('Content-Type' => 'application/octet-stream');

    $filetopath = $public_dir . '/' . $zipFileName; 
}

但它似乎没有创建zip文件,我无法下载它.请需要一些帮助

解决方法:

首先：if条件下的相同比较会触发我.

许多人可能不知道这一点,但ZipArchive::addFile()和ZipArchive::close()也返回布尔值以显示他们的成功(或失败).您应该始终检查它们,因为如果文件夹不可写,则只返回close方法.

然后你说如果你调用控制器动作就没有下载.那就对了.您没有告诉程序将某些内容流式传输到客户端.你只需设置两个变量,一个用于标题？另一个用于上面用于打开zip文件的完全相同的文件路径.

以下代码是一个工作示例(至少在具有正确文件夹权限的已配置环境中)此过程如何工作并为您的任务获得一些“灵感”.

public function testing() {
    // create a list of files that should be added to the archive.
    $files = glob(storage_path("app/images/*.jpg"));

    // define the name of the archive and create a new ZipArchive instance.
    $archiveFile = storage_path("app/downloads/files.zip");
    $archive = new ZipArchive();

    // check if the archive could be created.
    if ($archive->open($archiveFile, ZipArchive::CREATE | ZipArchive::OVERWRITE)) {
        // loop through all the files and add them to the archive.
        foreach ($files as $file) {
            if ($archive->addFile($file, basename($file))) {
                // do something here if addFile succeeded, otherwise this statement is unnecessary and can be ignored.
                continue;
            } else {
                throw new Exception("file `{$file}` could not be added to the zip file: " . $archive->getStatusString());
            }
        }

        // close the archive.
        if ($archive->close()) {
            // archive is now downloadable ...
            return response()->download($archiveFile, basename($archiveFile))->deleteFileAfterSend(true);
        } else {
            throw new Exception("could not close zip file: " . $archive->getStatusString());
        }
    } else {
      throw new Exception("zip file could not be created: " . $archive->getStatusString());
    }
});
