i am also using this

But both are not working. can anyone help me.

Answer 1

The crontab you have made will run every minute of every second hour rather than every two hours.

In order to get it to run every two hours you need something like this:

5 */2 * * * /usr/bin/php /var/www/html/sports/webservices/rss-insert.php

which will run it 5 minutes after every second hour eg 2:05, 4:05...

This is assuming your script is able to run. Try running the command portion from the cron by hand at the command line and make sure it does what you want.
