Who is the owner of the file, and how is the uid determined?

Question

linux

Created a test file on the server and displayed its data on the screen

$stat = stat($path);
print_r(posix_getpwuid($stat['uid']));

And here is the data itself

Array ( [name] => r33333 [passwd] => x [uid] => 1717 [gid] => 1715 [gecos] => [dir] => /home/r33333 [shell] => /usr/local/cpanel/bin/noshell )

Question - where did [uid] => 1717 and [gid] => 1715 come from - what is it?

Answer 1

name	The name element contains the user's name. This is a short, usually less than 16 character "handle" for the user, and is not the actual full name of the user.
id	Numeric user ID, must match the uid parameter passed when calling the function. Is redundant.
guide	The user's group ID. Use the posix_getgrgid() function to get the name of a group and a list of its member users.
