I need to run few php program concurrently every 5 seconds,
I had R&D on it, and know crontab unable to run in second, just minutes

Sure I had my reason to do it,
so I hope any expert can help me on it

but to make few php program run concurrently,
I need few shell script? or any better solution?

I am newbie in linux and just work hard on it,
really need your advice.

Thank you very much!

Crontab can do Second just do 0,xx minutes.
And for shell script you can use: "sleep 5"
But, I dont get why you want to run a PHP prog every 5 seconds.
You can also include that in the PHP script itself?
Or well I guess you can beter translate the script to Perl, C++ or something like that.
