tar没有保留目录结构

Question

I would like to tar a directory without retaining the directory structure, for example I am tarring like this

shell_exec('tar czf '. __DIR__ .'/tmp/'.$entry.'.tar.gz /home/minecraft/multicraft/servers/'.$entry);

This works fine and correctly but when I open the .tar.gz it is shown like this

I would like to not retain the directory structure just the folder contents without the directory structure. So like, the .tar.gz contains /home/minecraft/multicraft/servers/server1 I just would like to only have the contents of the directory server1 in the .tar.gz

contents of server1:

If anyone could be of any help on this, it would be greatly appreciated!

Use tar -C to change directory before creating the archive:

tar cz -C /path/to/dir . -f /path/to/archive.tar.gz
# archive.tar.gz gets contents of /path/to/dir as root entry:
# ./
# ./data.txt

If I got your PHP-code correctly, it would be something like:

$tar_dir = "/home/minecraft/multicraft/servers/$entry";
$archive = __DIR__ . "/tmp/$entry.tar.gz";
shell_exec("tar cz -C $tar_dir . -f $archive");
