dirname — Returns a parent directory's path
$path
[, int $levels = 1
] ) : string
Given a string containing the path of a file or directory, this function
will return the parent directory's path that is
levels up from the current directory.
Notă:
dirname() operates naively on the input string, and is not aware of the actual filesystem, or path components such as "..".
dirname() is locale aware, so for it to see the correct directory name with multibyte character paths, the matching locale must be set using the setlocale() function.
pathA path.
On Windows, both slash (/) and backslash (\) are used as directory separator character. In other environments, it is the forward slash (/).
levelsThe number of parent directories to go up.
This must be an integer greater than 0.
Returns the path of a parent directory. If there are no slashes in
path, a dot ('.') is returned,
indicating the current directory. Otherwise, the returned string is
path with any trailing
/component removed.

echo dirname("/etc/") . PHP_EOL;
echo dirname(".") . PHP_EOL;
echo dirname("C:\\") . PHP_EOL;

Exemplul de mai sus va afișa ceva similar cu:
/etc / (or \ on Windows) . C:\ /usr
