Re: php cron to check and remove files

I handle your object a different and, I believe, a simpler way. Instead of a cronjob, I call a cleanup function whenever a page is opened. Obviously, this approach requires a time overhead and thus is not good for very high volume sites. You can mitigate this drawback by maintaining a simple touch() file that keeps track of the time when your cleanup function is run and insure it only runs once a day, or whatever frequency you need. You can even make the file sticky so it stays in memory to further reduce the overhead. Steven Macintyre wrote:

Hi, I need to be able to do the following procedure; retrieve all items from a mysql db table, then check to see if the files from that table exist on the server (images), if not, to "clean up" and remove the physical file - so that only the files from the db exist. This will run via cron Has anyone done something similar before, willing to assist me with a basic scope of actions to work on? Thanks in advance Steven
