you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM

1 10 * * * php -f /var/www/package/index.php controller function

30 14 * * * php -f /var/www/package/index.php controller function

but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30 .

30 10,14 * * * php -f /var/www/package/index.php controller function

From cron manual http   man7 org linux man-pages man5 crontab 5 html      Lists are allowed   A list is a set of numbers  or ranges  separated   by commas   Examples   1 2 5 9    0-4 8-12     So in this case it would be   30 10 14
