Very quick review: - please use escapeshellarg() where ever exec is used... - unless it would break things.. (then at least make notes to such) - try using System::which() to discover /usr/sbin/iwconfig etc... in the constructor (normally for something like this I would have done var $cmds = array( 'ifconfig' => ..... , 'iwconfig' => .....) Groups related variables together , and concentrates code and documentation in a smaller more relivent group. |
