Hi, I'm trying to create a class CreateFile to create a .txt file. And a class CreateZip, which achieves a .zip file through one or more paths ... I can create the .txt files, but not .zip ... You have ideas?
My code:

    $file = new File;
    $file->data = 'file_input.txt';//fopen('/file_input.txt', "x");//Input::file('file_input.zip');
    $file->disk_name = $disk_name;
    $file->file_name = 'file_input.txt';
    $file->file_size = '2333';
    $file->content_type = 'application/txt';
    $file->is_public = true;
    $file->save();

    $fp = fopen($file->getLocalPath(), "w"); //fopen('/public/'.$path.$disk_name, "xw");
    fwrite($fp, '1');
    fwrite($fp, '23');
    fclose($fp);

with $file can I create the file on the disk and DB system_files and fopen and fwrite function bat in db content_type = inode/x-empty , file_size = 0
If .txt change in .zip $file does not work completely
Ideas?
Help me

Unfortunately, you cannot create an archive (or zip file) by just changing the extension. A zip file is completely different to a txt file (just look at it by opening both of them in a text-editor like Notepad, Sublime Text or Notepad++.

Since it's not that simple to create a class that handles zip archive (de)compression. I would recommend you head over to packagist and look for appropriate packages (like this for archive (de)compression). These packages are much more reliable, more widely used, and better tested.

Thank you
