Unable to access xampp files because of user permissions problem

Question

I've installed xampp on my MacBook with macOS 10.12, Sierra. Everything works fine, but I created php app with slim framework witch creates cache files.

The problem is that I have no permissions to these files, I can not delete them because this files belongs to user daemon.

I've tried to change user in xampp https.conf but when I change user to my username apache will not start:

ERROR: Failed to restart "apache": cannot stop service: AH00543: httpd: bad user name

Anybody know how to deal with this problem?

UPDATE:

folder path is nfs://192.168.64.2/opt/lampp/htdocs/2017/cache

I try this command when I am in 2017 folder:

sudo chmod -R +a "staff allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit" cache

And i get

chmod: Failed to set ACL on file 'cache': Operation not supported

chmod: Failed to set ACL on file '5d': Operation not supported

chmod: Failed to set ACL on file 'dc': Operation not supported

chmod: Failed to set ACL on file '5ddcda0f8a5b896924f37eaa7d4701bffab1d462': Operation not supported

sudo chmod -R 777 cache

chmod: Unable to change file mode on cache/5d: Operation not permitted

chmod: Unable to change file mode on cache/5d/dc: Operation not permitted

chmod: Unable to change file mode on cache/5d/dc/5ddcda0f8a5b896924f37eaa7d4701bffab1d462: Operation not permitted

UPDATE

Problem solved by install older version of xampp witch files are not in network shared folder but in /Applications/Xampp

There is no problem with virtual hosts and folders permissions

Network Drive Limitation

You likely can not change the permissions of using the network shared drive, nfs, path. Instead use the approach below on the Mac involved, using the local paths.

Changing Permissions

You can grant yourself access to the daemon's files using the Finder's Get Info panel.

1. Within the Finder, select the folder you want access to;
2. Select File (menu) > Get Info;
3. Within Sharing & Permissions click the + and add your user account;
4. Within Sharing & Permissions click the cog and select Apply to enclosed items.

You may need to unlock the permissions settings using the Lock on the lower-right of the panel.

Command line approach

Alternatively, you can use the command line to change permissions, see Permissions for new files in shared directory. The command line approach is more capable and allows sudo to ensure you have permissions to make the change.
