Delete the file manually for day to day process

I've created a l开发者_JAVA技巧og file for day to day processing and i want to delete the old files generated before 2 days.

In case you use Linux

find /var/spool/sms -mtime +2 -type f | xargs rm -f

All files in /var/spool/sms older than 2 days will be deleted.

PHP unlink — Deletes a file

Probably if you are on LInux platform you can use cron .
