Re: [PHP] Start/stop daemon using php
Hi, You might consider D-BUS for your application and the D-BUS PHP binding which is available since some days too. This would allow you to start / stop your C application in a far more secure way than the suggested one. Please have a look at my original release annoucement at the D-BUS mailing list: http://lists.freedesktop.org/archives/dbus/2008-February/009363.html as well as the download URL: https://sourceforge.net/project/showfiles.php?group_id=17176package_id=68954 Even if the application runs on Windows you might be able to use D-BUS for communication.
