php and crontab

hi,
could you tell me please how can i use crontab with php.
steps to explain for me how and where to put the crontab.
thanx

I will try, I love using php this way.

crontab -l (displays what is currently in crontab)
crontab -e (edit the current crontab, opens w/default editor)

The syntax for cron is:
minute|hour|day of month|month|day of week|command

You need to make sure that you have access to cron. Check files /etc/cron.allow, /etc/cron.deny

For more info on that check the man pages for crontab specifically crontab(1) and (5).

Create a php file, ie cli.php, like you normally would (minus the html), make sure that it is executable. Then for the command part of crontab do something like this:
php -q /path/to/file/cli.php

Thats it!

Here is an example of a statement in my crontab:
30 19 3 19 * php -q /home/evilive/icommish_jobs/48hrs.php

This basically reads:
On the 30th minute of the 19th hour on the 3rd day of the 9th month on any day of the week execute 48hrs.php

Hope that helps.
