note 64067 added to function.shell-exec

A question...i am making a web interface of nmap using php, ofcourse. As an example i use $result = Shell_exec("nmap -sS -O 172.134.4.3); print($result); BUT it doesn't give the output. On carefully looking at the bar below in the interface window...i noticed.... >>>> data is being transferred... and then >>>> done. How do i execute such commands using php and display the output.
