Can't control volume using PHP exec command and NirCmd

Question

I'm running wampserver 2.2 on Windows 7, and I'm trying to use NirCmd to mute windows volume. My code is:

<?php
exec("c:\nircmd\nircmdc mutesysvolume 1");
?>

The command seems to work well, and mute my sound when run not via PHP, but doesn't work through PHP.

Help anyone? Or any other suggestions on how to make a remote control using PHP?

Thanks

Answer 1

The sequence \n inside a double-quoted string resolves to a newline character, destroying your path.

You can use single quotes instead:

exec('c:\nircmd\nircmdc mutesysvolume 1');

Or, even better, use forward slashes instead of backslashes to avoid the problem entirely:

exec('c:/nircmd/nircmdc mutesysvolume 1');

Answer 2

if you use double quoted string do it like ( and try .exe ). Or like "Jon" said use forward slashes.

exec("c:\\nircmd\\nircmdc.exe mutesysvolume 1");
