PHP：使用glob（）列出* .txt和目录？

Question

Instead of listing all the files and directories

foreach(glob("/*") as $file) {
    ...
}

Is there a way to filter *.txt files and directories? Because with this example

foreach(glob("/*.txt") as $file) {
    ...
}

Will only get the *.txt files, but not the directories. But to list only directories, this will work:

foreach(glob("/*", GLOB_ONLYDIR) as $file) {
    ...
}

but will left out the *.txt files. I am trying to avoid using preg_match() or similar operations post reading the directory because it will waste server resources if there are around 5000 unnecessary files (image files with *.jpg, *.png).

Thank you.

Also tried GLOB_BRACE, but it didn't work, so had to use the following code:

$aDir1 = glob('/*.txt');   // current directory
$aDir2 = glob('/*/*.txt'); // subdirectory, one level below

$aDir = asort(array_merge($aDir1, $aDir2));

Thank you.
