轻松设置文件夹结构

Posted 2021-02-26

Here is a function you can use to automatically set up a complex folder structure with a specified file mode. All you have to do is create the "root" directory and pass an array describing the folder structure you would like to create in it. If the directory already contains a part of the desired directory structure, the script will set the specified file mode on every existing folder. There's an example how to use the function at the bottom of the snippet.

I use this to set up user home's. I tested this with php 5.2.11 on Apache running on Mac OS X. It should work on most Linux servers. It won't work on Windows.

This function should be easy to modify for your needs or integrate into a class. Have fun.

<?php
 
/**

 * @param   string   Path to directory where $dir_structure should start creating dirs
 * @param   array    Associative array describing directory structure.
 * @param   integer  Optional file mode to create and check folders for. Defaults to 0755
 */
function create_folder_structure($base_path, $structure, $file_mode = 0755)
{
  foreach ($structure as $key => $value)
  {
    if (!file_exists($base_path))
      throw new Exception(sprintf('Directory "%s" does not exist', $base_path));
 
    // value can be either the directory name or an array containing deeper directory structure
    $dir_name = is_string($key) ? $key : $value;
    $path_to_dir = $base_path.'/'.$dir_name;
 
    // create directory or set permissions
    if (!file_exists($path_to_dir))
      mkdir($path_to_dir, $file_mode);
    else
      chmod($path_to_dir, $file_mode);
 
    if (!file_exists($path_to_dir) || !is_readable($path_to_dir) || !is_writeable($path_to_dir))
      throw new Exception(sprintf('Cannot create or set file mode for directory "%s" to %d', $path_to_dir, $file_mode));
 
    // create any deeper directory structure recursively
    if (is_array($value))
      create_folder_structure($path_to_dir, $value, $file_mode);
  }
}
