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

dirname(). 您可以根据需要多次使用它

  • to get parent/child - dirname('parent/child/reply')
  • to get parent - dirname(dirname('parent/child/reply'))
  • 获取父/子 - dirname('parent/child/reply')
  • 获取父级 - dirname(dirname('parent/child/reply'))

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

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

这是一个删除URL后n部分的函数:

/**
 * 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;
}
