Problem while extracting zip file - Ziparchive

Question

I created a script to generate one (Backup/Restore) files on my system, it works perfectly on "location-windows" both the backup and the restore, however when going up in "hosting-linux" happens the following.

1. First i Gero the local backup and go up on the hosting.
2. in the hosting I restore this backup.

Only that it takes the address of the files and generates only one getting like this:

instead of creating the structures it merges everything into one, to be even more specific see in line 3 in the image, it was to create the application | Configuration | functions-groups folders and then the Admin.php file but joined everything.

Obs: if in the hosting I generate the backup and restore it works perfectly, if I take a zip file any generated "local" and rise also works in the hosting.

I don’t know if this is the case but the accommodation is hostgator and php version on site/hosting is 7.3

index php.
