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.

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.
