How is PHP supposed to know if a file is not needed? Are you comparing the files in a directory to a list of files that are not needed, comparing to database enteries, or something else?

zq29 Posted June 19, 2006 Share Posted June 19, 2006 You could probably do this be creating two arrays, one containing all of the files referenced in the database and the other containing all of the files actually in the directory. Compare the two arrays, and delete any files from the directory that are returned by the comparisson.Heres the functions I'd use...glob() - To get an array of files from a directoryarray_diff() - To compare the two arraysunlink() - To delete filesMixed with the usual MySQL functions and control structures.
