Answer 1

dirname(). You can use it as many times as you'd like

• to get parent/child - dirname('parent/child/reply')
• to get parent - dirname(dirname('parent/child/reply'))

Answer 2

Here' is a function to remove the last n part of a URL:

/**
 * remove the last `$level` of directories from a path
 * example 'aaa/bbb/ccc' remove 2 levels will return aaa/
 *
 * @param $path
 * @param $level
 *
 * @return mixed
 */
public function removeLastDir($path, $level)
{
    if (is_int($level) && $level > 0) {
        $path = preg_replace('#\/[^/]*$#', '', $path);

        return $this->removeLastDir($path, (int)$level - 1);
    }

    return $path;
}

Answer 3

    preg_replace("/\/\w+$/i","",__DIR__);
     # Note you may also need to add .DIRECTORY_SEPARATOR at the end.

Answer 4

dirname($path)

And this is the documentation.
