Php recursively traverses the file tree code. The Glob function performs better on recursive scanning of the folder tree. The Scandir function does not scan the files at .. twice. that is to say, if the problem of recursive scan of the folder tree is a little better than the Glob function, it is very accurate. > The Scandir function may scan files at ../twice, that is, if there are two files in Xiao Xie.
> ../B. php Tutorial and ../a. php, the results will appear twice in the scan report, which is very strange.

The Glob function performs better and is very accurate. > The Scandir function will scan the file at ../twice, that is, if it is small...
