Check if directory have sub-directories PHP

Question

I am trying to get a file in a directory. This operation must be very fast.The inital directory can have childrens like path/child/sub_child/sub_sub_child/aFile. But a file can also be present before

• Path

  • Child
  • A file

  I do not care about which file I am getting I just want a fast way to get it.

I am stuck with this

        $h = opendir($path); //Open the current directory
        while (false !== ($entry = readdir($h))) 
        {
            if($entry != '.' && $entry != '..') 
            { 
                echo $entry; 
                break; 
            }
        }
