note 29147 added to function.system

I am trying to get the system function to execute gpg. with: $command = "/usr/bin/gpg -a --recipient 'user1 key' --encrypt -o $outfile $infile"; system($command, $result); gpg is working fine, but the system function is doing nothing. I get no return value. Any ideas why this is occuring? -- http://www.php.net/manual/en/function.system.php http://master.php.net/manage/user-notes.php?action=edit+29147 http://master.php.net/manage/user-notes.php?action=delete+29147 http://master.php.net/manage/user-notes.php?action=reject+29147
