Answer 1

your variable $view_data only gets defined in the first if statement. It looks like in the if statement below that you are using $view_data even though it hasn't been set.

if(!is_readable($file)){
    throw new Exception('view file application'.DS.'views'.DS.$view_data[0].DS.'view.'.$view_data[1].'.php not found.');
}

You either need to set $view_data in your else statement, or in the exception above, use the $file variable that you've already set:

if(!is_readable($file)){
    throw new Exception('view file '. $file .' not found.');
}
