是否可以使用glob从根目录和子目录中获取文件？

Question

I'm working on a script that when ran uses glob() to get all the files from a directory that is passed through an arg, and then check their modification time. Is it possible to have glob() go through the files in the dir, and the files in the sub dirs?

Answer 1

Is glob() a requirement? For a recursive implementation I prefer using RecursiveDirectoryIterator(). This does the same job in a much more readable way.

$realpath = realpath('/path/to/file');


$fileObjects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($realpath));

foreach($fileObjects as $key => $object){
    echo $object->getFilename();
}
