递归树文件夹函数php不进入子文件夹

Question

我目前正在开发一个php文件索引器，我需要创建一个递归函数来创建一个数组，该数组将包含父文件夹的文件和子文件夹列表，子文件夹也是包含它们的文件及其子文件夹的数组(等等)。由于这是一个学校项目，我不能使用DirectoryRecursiveIterator和它的兄弟姐妹RecursiveIterator和DirectoryIterator。我的问题是，它扫描父文件夹并找到子文件夹和文件，但不会在子文件夹中查找文件和子文件夹。

代码

<?php
    class H5AI
    {
        // Properties
        private $_tree;
        private $_path;
    
        // Construct
        public function __construct($_path)
        {
            $_tree = [];
            $parent = $_tree;
            print_r($this->getFiles($_path, $parent));
        }
    
        // Methods
        public function getPath()
        {
            return $this->_path;
        }
        public function getTree()
        {
            return $this->_tree;
        }
    
        public function getFiles($path, $parent)
        {
            //Opening the directory
            $dirHandle = opendir($path);
            while (false !== $entry = readdir($dirHandle)) {
                //If file found
                if (!is_dir($path . DIRECTORY_SEPARATOR . $entry)) {
                    array_push($parent, $entry);
                }
                // When subdirs found (ignore . & ..)
                else if (is_dir($path . DIRECTORY_SEPARATOR . $entry) && $entry !== "." && $entry !== "..") {
                    $newPath = $path . DIRECTORY_SEPARATOR . $entry;
                    $parent[$entry] = [];
                    $this->getFiles($newPath, $parent[$entry]);
                }
            }
            return $parent;
        }
    }
    // Calling function
    $h5a1 = new H5AI($argv[1]);
    
    // Command I use in the terminal
    php index.php "./test_dir"

    //Output
    Array
    (
        [sub_test_dir] => Array
        (
        )

        [0] => test.css
        [sub_test_dir2] => Array
        (
        )
        [1] => test.js
        [2] => test.html
     )

class H5AI {

  public function __construct(string $path) {
    print_r($this->getFiles($path));
  }

  public function getFiles(string $directory): array {
    $handle = opendir($directory);
    $entries = [];
    while (true) {
      $entry = readdir($handle);
      if ($entry === false) {
        break;
      }
      $path = $directory . DIRECTORY_SEPARATOR . $entry;
      if (is_file($path) && !str_starts_with($entry, '.')) {
        $entries[] = $entry;
      } elseif (is_dir($path) && !in_array($entry, [ '.', '..', '$RECYCLE.BIN' /* add other dir names to exclude here */ ])) {
        $entries[$entry] = $this->getFiles($path);
      }
    }
    closedir($handle);
    return $entries;
  }
}

您正在创建一个单独的数组，该数组包含所需内容，但未插入到父数组中。你把一切都做好了，你只需要一个小小的修正：

                //...
                else if (is_dir($path . DIRECTORY_SEPARATOR . $entry) && $entry !== "." && $entry !== "..") {
                $newPath = $path . DIRECTORY_SEPARATOR . $entry;
                $parent[$entry] = [];
                $parent[$entry] = $this->getFiles($newPath, $parent[$entry]); // <-- fix is on this line
            }
