How to use Cron Jobs to execute PHP regularly under Cpanel

The basic format of crontab is:

The first column of the time-sharing, day-month-week command indicates minutes from 1 to 59. Each minute is represented by * or */1. The second column indicates hours from 1 to 23 (0 indicates 0 o'clock).
The third column represents the date 1 to 31
