I use php for my Static Web Sites, But Do I need to use an MVC framework for A Professional Static Site, What will be the advantages and disadvantages of using one for A Static Site? What are the frameworks that are more suitable for Static Web Sites? So far I did not use any framework for my Static Website Creations, But I thought if it is good to implement a framework to professionalize my work.
You don't need to use MVC framework for static site, because I think you are not going to make any changes in your static website after deploying on server.
But if you have a Professional Static Site, I suggest to use a good framework which is best suitable for you.
Every PHP MVC framework have their own advantages and disadvantages, so only think about advantages of framework. And how that framework is capable of completing and full-filling your requirement.
For your Professional Static Site, I suggest to use Wordpress, Joomla, Drupal, etc frameworks which are best suitable for you.
Good luck.
