php that stops executing after 2 hours

[MidOhioIT]

I have a newsletter system that is coded with php to mysql.  It is trying to do almost 60,000 emails.  Everything works fine except at around 2,000 emails which is around 2-3 hours worth of processing the script always seems to stop running.  is there a setting or a command that I can run to keep it running until the end?  I can provide the code if needed but thought maybe it is a simple comand i can just insert (i hope)

Run it from the command line and make sure that you give it enough memory.

put

set_time_limit(0);

at the top of the script. To be honest you would be better queueing these up in a mysql table and sending them in small batches every so many minutes (say 200 every 15 minutes) and help spread the load over time - That plus you can have the same script running multiple times. By your current guesses the 60000 could last between 60 to 90 hours, which is madness to be honest
