Use CLI then? Personally I do not think that CGI version is the best choice for daemons, as it wasn't designed for such purposes. Previous Comments: ------------------------------------------------------------------------ [2004-10-23 20:28:39] toppi at kacke dot de Hi Tony, it doenst work. STDIN is not defined/open. When i understood the manual correctly, its only defined when using cli sapi. I have php -v PHP 5.0.2 (cgi) (built: Oct 23 2004 14:07:24) I tired a lot of things, to kill the stream and getting disconnected...but nothing helped yet. When i remember me right, we didnt have that prob @ 4.3.x. but not sure tho. I have no clue anymore :) ------------------------------------------------------------------------ [2004-10-23 17:40:51] [EMAIL PROTECTED] fclose(STDIN); after successful fork() call should help you. ------------------------------------------------------------------------ [2004-10-23 15:01:21] toppi at kacke dot de Description: ------------ After forking a process and setting the child as sessionleader (becomes deamon) you cant disconnect from the current terminal-session (exit) solong the child is in process. After typing exit, the terminal prints the output from the child again.
