PHP 递归函数的应用(二) 文件夹目录遍历

文件夹目录的遍历同样也利用递归去一层一层的遍历文件

以下面这个目录为例的

//$onlyDir 是否只输出目录
function dirList($dir, $onlyDir = true)
{
    $result = array();
    $handle = opendir($dir);
    if ($handle) {
        while (($file = readdir($handle)) !== false) {
            if ($file != '.' && $file != '..') {
                $cur_path = $dir . DIRECTORY_SEPARATOR . $file;
                if (is_dir($cur_path)) {
                    $result[$file] = dirList($cur_path, $onlyDir);
                } else {
                    if (!$onlyDir) {
                        $result[] = $file;
                    }
                }
            }
        }
        closedir($handle);
    }
    return $result;
}

运行dirList('/web/mall/Application/lib', false)
打印数组

array(3) {
  ["Action"]=>
  array(3) {
    ["Admin"]=>
    array(10) {
      [0]=>
      string(20) "GoodAction.class.php"
      [1]=>
      string(21) "IndexAction.class.php"
      [2]=>
      string(21) "LoginAction.class.php"
      [3]=>
      string(20) "MenuAction.class.php"
      [4]=>
      string(21) "OrderAction.class.php"
      [5]=>
      string(22) "PublicAction.class.php"
      [6]=>
      string(20) "UserAction.class.php"

      string(20) "UtilAction.class.php"
      [8]=>
      string(22) "WechatAction.class.php"
      [9]=>
      string(22) "WeixinAction.class.php"
    }
    ["Api"]=>
    array(1) {
      [0]=>
      string(19) "ApiAction.class.php"
    }
    ["App"]=>
    array(2) {
      [0]=>
      string(21) "IndexAction.class.php"
      [1]=>
      string(13) "Sms.class.php"
    }
  }
  [0]=>
  string(7) "log.txt"
  ["Model"]=>
  array(2) {
    ["Admin"]=>
    array(1) {
      [0]=>
      string(20) "OrderModel.class.php"
    }
    ["App"]=>
    array(1) {
      [0]=>
      string(20) "OrderModel.class.php"
    }
  }
}

可以很清晰的看出一层一层的结构
