從多維數組中找到文件路徑

Question

我得到了下面的目錄數組。

我將在這個數組中進行文件搜索。例如path.php，survey.php ... 如果找到文件，應該如何構建路徑。

爲path.php

我想函數返回 '/survey/config/path.php'

Array 
(
[survey] => Array 
    (
     [config] => Array 
      (
       [0] => path.php 
       [1] => routes.php 
      ) 

     [controllers] => Array 
      (
       [0] => admin.php 
       [1] => giris.php 
      ) 

     [models] => Array 
      (
       [0] => giris.php 
      ) 

     [views] => Array 
      (
       [0] => admin_form.php 
       [1] => widget.php 
       [2] => yeni_form.php 
      ) 

     [widgets] => Array 
      (
       [0] => survey.php 
      ) 

    ) 

）

function find_file_path($dir_structure, $filename) { 
    foreach($dir_structure as $dir => $subpath) { 
     if(is_array($subpath)) { 
      $sub_found = find_file_path($subpath, $filename); 
      if($sub_found) { 
       return "/" . $dir . $sub_found; 
      } 
     } else { 
      if($subpath === $filename) { 
       return "/$filename"; 
      } 
     } 
    } 
    return FALSE; 
}
