Delete session files with CRON

Anon

hi,

i need to delete session files after "n" minutes of their last use.

i need the code in php that i could execute using a cron job.

this script should check all files in a directory.

i was wondering if there's such a function as:

foreach(file_in_this_directory) blah blah

please help.

i know how to use the cron to execute files after "n" minutes. i just need a code in PHP that would check ALL files in a directory for there last use - a timestamp or something.

your help would be greatly appreciated.

Check the manual for:

opendir(), readdir(), closedir() (under "Directory functions"), fileatime(), filemtime(), unlink(), is_file() ("Filesystem functions"), while(){} ("Control structures")

Also, search-the-whole-directory thing appeard on this forum many times, so you may want to search it.

If you get stuck with something specific, feel free to post.

P.S. Be careful for "special" dirs: "." and "..".

is_file() will return false for all directories, including "." and "..". Of course, if these are only directories, no need to bother yourself with full file names (required by is_file()). You can use

...$f = readdir(...)...
if (($f != ".") && ($f != "..")) ...use $f...

if (!(ereg("^.{1,2}$", $f)) ...use $f...

oh i c, i tried to use the "if" with the "or/and" but i had forgotten the additional brackets.

thanks
