Run php script every X seconds

Heya

 

I need to run a PHP script every X seconds, so I tried using cron with sleep but I can't have them overlapping...any simple solution for this?

use touch() to create a lock file -- a blank file, with any name you want.

 

at the very beginning of the script check for the existence of the lock file(is_file()), if it exists exit(), else proceed

 

then use unlink() to remove the lock file when the script is complete
