[PHP] forking off in php
hello, I have what may seem like a small problem but its not obvious to me. I have a script that I forked and that part works fine, it forks, tells me the pid like I wanted, and keeps running. Well, the problem that was not apparent to me until about 3 days ago when I was wondering why the script(my php chat server) was crashing at seeminly random times. I finally figured out that when I logged out of my shell in linux, the talker would go down as well. Obviously I don't want that but what do I need to add to the line when i start the script thanks matt ps If it helps, I am running php 4.3.10 on slackware -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Works great for me - I've had PHP daemons running for over 9 months without a break.

Add '' i.e. You don't need to do that - the forking script will start, spawn a child process then exit, so adding will do nothing. Having said that, you could achieve something similar by not forking and using nohup (look it up with man) with , however, that will mean it runs as you, whereas a forked process can easily switch users and drop privileges for increased security.
