Get only the path for a file

Sometimes it is required the get only the path that a file exists. In such cases following function could be of some help. I
hope this function helps someone like me

     function getPath($path) {
         if(substr($path, -1, 1) == '/') {
             return $path;
         }
         else {
             $pathArr = explode('/', $path);
             $total = count($pathArr);
             $end = $pathArr[$total - 1];
             if(substr_count($end, '.') > 0) {
                 array_pop($pathArr);
             }
             $finalPath = implode('/', $pathArr);
             return $finalPath;
         }
     }
?>
