如何使用php获取所有文件夹子文件夹而不使用文件名

Question

我想获得所有列表文件夹和子文件夹，只有文件名和文件名 示例输出：

folder name:
source/1
source/1/2
source/1/2/3

filename
0.jpg
1.jpg
3.jpg

这是我的代码，此代码工作正常，但此代码显示文件名为..

$rootpath = 'source';
$fileinfos = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($rootpath)
);
foreach($fileinfos as $pathname => $fileinfo) {
    if (!$fileinfo->isFile()) continue;

echo($pathname).'<br>';


}

修改 如何使用正则表达式或preg-match FOLDERNAME /子文件夹/ filename.jpg

如何仅获取foldername/subfolder/且仅filename.jpg

$filepath = 'foldername/subfolder/filename.jpg';

$folder= (preg_match('~[^A-Za-z0-9_\./\]~', $filepath));
echo 'folder:' .'<br>' .$folder;

$filename =(preg_match('....', $filepath));

echo 'fileneme' .'<br>' .$filename;

输出

folder:
foldername/subfolder/

filename:
filename.jpg

下面的代码段可能有所帮助。如果您决定只获得FILES;只需传递String＆＃39;文件＆＃39;作为函数scanDirRecursive的第3个参数。默认情况下，该函数返回给定目录中所有DIRECTORIES和SUB-DIRECTORIES的列表：$directory（第一个参数）。然而;你可能仍然得到DIRECTORIES＆amp; FILES一气呵成。
要做到这一点;只需传递字符串：both作为第3个论点....

希望这对你有所帮助。
CHEERS＆amp;好运!!!
