Hello I would like to know, what does all that stuff with /dev/null and all the different varieties at the end of the nohup command mean and also why is there a '&'. Please some explanation or please a tutorial for stuff like that, thank you =)
shell_exec("nohup ... </dev/null 2>/dev/null >/dev/null &");
shell_exec("nohup ... </dev/null 2>/dev/null >/dev/null &");
