it depends on how you wanna do it, you can either install the lynx text editor on the nix box and run the php page that way or use wget (most nix platforms have this installed by default)
then use something like
- lynx -dump full/path/to/script >dev/null
or
- wget -o full/path/to/script >dev/null
1st - Minutes after the Hour
2nd - Hours of the Day
3rd - Days of the Month
4th - Months of the Year
5th * - WeekDays of the Week
This would do an hourly cron with lynx
0 lynx -dump full/path/to/script >dev/null
