How to run the PHP script at scheduled time

Question

I need to run a php script at the scheduled time daily to update some fields in database and to send automated email. How I can do this?

Is it possible to write so

Answer 1

PHP cannot run script by itself,since php doesn't have daemons like python !! So you have to take OS help to invoke your custom script .

For example in linux : (example.sh) export USE_PHP=php cd $SCRIPT_ROOTDIR $USE_PHP -f cronfile.php service="checkdatabase" (service is the parameter passed to your cronfile).

For setting up cron jobs ,have a look at this link http://www.cyberciti.biz/faq/how-do-i-add-jobs-to-cron-under-linux-or-unix-oses/
