Warning: include(../views/product_index.php): failed to open stream: No such file or directory in C:\Users\giuliano\PhpstormProjects\mvc\controllers \ProductController.php on line 12

Warning: include(): Failed opening '../views/product_index.php' for inclusion (include_path='.;C:\php\pear') in C:\Users\giuliano\PhpstormProjects\mvc\controllers \ProductController.php on line 12
