Answer 1

To get the output, you need to pass a second parameter, or you can get the last line of output by echo'ing it.

From the PHP manual:

string exec ( string $command [, array &$output [, int &$return_var ]] )

Return Values:

The last line from the result of the command. If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function. To get the output of the executed command, be sure to set and use the output parameter.
