Almost right. It's UGO, User Group and Other.
When you view a PHP page, it's (usually) served by Apache, the process
will be owned by a user, usually 'apache'; who is also a member of a
group, usually 'apache'. On some systems these users/groups can be
'httpd', 'www-data' etc. When you or I look at a PHP file served from
Apache, there is no concept of users/groups/others outside those that
apply to the Apache process that served the data.

It's a seperate thing, because once again inside PHP there is no
concept of users/groups outside the Apache process itself. It would be
up to your PHP code to manage who has access to what, the files will
all be read from and written to disk by the Apache process.
