Php 只获取主文件夹，不获取子文件夹

我想获取没有子文件夹的主文件夹，代码如下：

$dir = new RecursiveDirectoryIterator($admin['data_folder_main'], FilesystemIterator::SKIP_DOTS);
$it = new RecursiveIteratorIterator($dir, RecursiveIteratorIterator::SELF_FIRST);
$it->setMaxDepth(1);

foreach($it AS $fileinfo) {
    if($fileinfo->isDir() AND !$it->isDot()) {
        echo $it->getSubPathName().'<br>';
    }
}

RecursiveDirectoryIterator

或

RecursiveIteratoryIterator

是否具有表示“这是主文件夹”的函数？还是我必须使用一些变通代码？如果是，代码会是什么样子？

不用担心！我是这样修复的：

$dir = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($admin['data_folder_main']), FilesystemIterator::SKIP_DOTS, RecursiveIteratorIterator::SELF_FIRST);

foreach($dir as $name => $object) {
    if($dir->isDir() AND !$dir->isDot()) {
        echo basename($name);
    }
}

当您只对第一级感兴趣时，为什么要使用递归迭代器？你能举个例子说明你想完成什么吗？

$dir = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($admin['data_folder_main']), FilesystemIterator::SKIP_DOTS, RecursiveIteratorIterator::SELF_FIRST);

foreach($dir as $name => $object) {
    if($dir->isDir() AND !$dir->isDot()) {
        echo basename($name);
    }
}
