You can still use Cronjob with 1 min setting and in use 2 processes
1. Run script immediately
2. Sleep for 30 sec and then run the script
you can use exec/shell_exec functions with output redirected to soem file so
that It will run in background.
That way you have one process running at 0 sec and one running at 30 sec
every minute

Thank you all
but the problem is that I don't have root access to the server to
create daemon :)
so if I just run the script in background with 30 seconds sleep and
someone reboot the server (or the script dies for any reason ) I will
lose my process :)
any other ideas ?
is it possible to link the script to my php interface (the one that
the users is using it) and if the php interface page will run the
script (IN background) if it didn't run for the last 30 seconds ? I
see this is very hard and almost impossible , what do you think ?
PS: also I need to make sure no more than 1 process of the script is
running :)
