When i execute following none works (checked with ps aux | grep mplayer, where 1.wav is a 10 minutes audio file):
system("mplayer /tmp/1.wav"); // failed
system("sudo -u myusername mplayer /tmp/1.wav"); // failed
system("mplayer /tmp/1.wav &"); // failed
system("(mplayer /tmp/demo.wav) >/dev/null &"); //failed according to: http://www.php.net/manual/fr/function.system.php#88543
system("sudo -u myusername -i mplayer /tmp/demo.wav");
How can i run a background process with PHP? Only this works but its like batch file and i am in the same system. $ php -r "system('mplayer /tmp/demo.wav');";
Thank you

You can use this with Linux configuration of sudoer. And then it works without password prompt.
