Re: touch()ing it....advise needed.

Hey, Heres my setup, I have a directory full of files and I get a request with an array of filenames For this example: a.txt b.txt c.txt if the above files dont already exist I need to create them (I am using touch() instead of fopen()) My question is which would you recommend, doing a readdir() and getting all the existing filenames in an array then doing a loop to see which exists and create the others OR just taking the new filenames, doing a while/for loop with a files_exists() on each and then creating the files.... I am favouring the second approach as in the first approach there are a lot of files the array could be pretty big which would cause other problems, but I would rather be corrected now if my thinking is flawed. Your advise appreciated.

Umm... How about option 3... Just touch() the file in a while/foreach loop <important> I *think* it will just set the mod/access time if the file exists and create an empty file if it doesn't. Might want to test to be sure though just to make sure it doesn't wipe the file, but I don't think it does. </important> This is assuming that the mod/access time isn't used for anything else so if it's randomly updated it won't matter. You save a file_exists() call this way too. Ed
