Deleting file every night

mattejonss

Hello!

I have a online counter and a counter that shows the amount of user per 24h. The counter decrease by one when a logged IP has been there for 24h.
But I want a counter that deletes the file say every night 0100 and starts counting from zero again.

So, please give me an example snippet that erases a textfiles content every night.

Thanks in advance!

Use cronjob for this.

Its a unix/linux feature. You can get the web server to run a script every night, i.e. tell it to run counter_reset.php at 1:00am

crontab -e \n
05 01 * rm /path/to/deleteme.log\n
\n

This is the most expeditious way to perform the desired action. Isn't it?

Additionally, in lieu of crontab access, you can create a flag file which you check the date on. If it has yesterday's date, kill the actual file in question, and touch() the flag file.

Of course, this assumes you have access to the crontab on the box (which most ISP's wont let you near 🙁 )

If you cant do it this way, try letting your script check the time/date stamp on the file when it hits it. If the time/date stamp is today then just add to the file... if it is for an older time, then remove the file and add your entry to a new file.
