如何一遍又一遍地运行.php文件... cron也许？

Question

I have a php file that calls exec() on a c++ exe.When the .exe is finishing running I need to run the php file again,repeat .

I am wondering what is the best way to do this? This .php file has no user interaction and needs to be completely automated.

EDIT:Found another solution that would kill the process if it is already running which will cover this issue well.See posts on this page.

I haven't used codeigniter before but there seems to be a solution as described in the wiki.

Depending on how you can access the system (if you are admin or not) and depending on how you are planning to update the automated commands, IMHO, you could use both solution (Linux crontab or codeigniter cron script).
