In programming there are a number of ways to execute on an idea and get a result, executing a php file on your web server is no different. Below I will provide examples of how to execute a php script or other type of script over http using configurable cron jobs.
Just about all webhosts also provide a method of adding cronjobs through their control panels including cpanel and plesk.
Method 1: Execute the script using php from the crontab
Just like how you call your shell script (As show in our crontab 15 examples article), use the php executable, and call the php script from your crontab as shown below.
To execute myscript.php every 1 hour do the following:
# crontab -e 00 * * * * /usr/local/bin/php /home/john/myscript.php
