获取目录中的最后修改文件 [英] Get last modified file in a directory

问题描述

有没有办法只选择目录中的最后一个文件(扩展名为jpg|png|gif?)

Is there a way to select only the last file in a directory (with the extensions jpg|png|gif?)

还是我必须解析整个目录并使用filemtime检查?

Or do I have to parse the entire directory and check using filemtime?

推荐答案

是的，您必须通读它们.但是，由于目录访问已缓存，因此您不必担心.

Yes you have to read through them all. But since directory accesses are cached, you shouldn't really worry about it.

$files = array_merge(glob("img/*.png"), glob("img/*.jpg"));
$files = array_combine($files, array_map("filemtime", $files));
arsort($files);

$latest_file = key($files);
