Yesod vs Yii: What are the differences?
Developers describe Yesod as "A RESTful Haskell web framework built on WAI". Yesod believes in the philosophy of making the compiler your ally, not your enemy. We use the type system to enforce as much as possible, from generating proper links, to avoiding XSS attacks, to dealing with character encoding issues. In general, if your code compiles, it works. And instead of declaring types everywhere you let the compiler figure them out for you with type inference. On the other hand, Yii is detailed as "A high-performance PHP framework best for developing Web 2.0 applications". Yii comes with: MVC, DAO/ActiveRecord, I18N/L10N, caching, authentication and role-based access control, scaffolding, testing, etc. It can reduce your development time significantly.
Yesod and Yii can be categorized as "Frameworks (Full Stack)" tools.
"Haskell" is the primary reason why developers consider Yesod over the competitors, whereas "Open source" was stated as the key factor in picking Yii.
Yesod and Yii are both open source tools. It seems that Yii with 4.86K GitHub stars and 2.22K forks on GitHub has more adoption than Yesod with 2.11K GitHub stars and 329 GitHub forks.
According to the StackShare community, Yii has a broader approval, being mentioned in 58 company stacks & 32 developers stacks; compared to Yesod, which is listed in 5 company stacks and 5 developer stacks.

Of all PHP frameworks, my best and only choice is Yii . Think of this: you have a MySQL database, it contains several tables. Now you want to setup a PHP-MVC site, firstly, you must create Models, Yii have a very handy tool called Gii, you can easily create model with Gii just by one click, Gii will read your database table columns and create PHP models automatically for you. Now you need Controller, still with Gii, it will automatically create all 4 php files for you with Insert/Delete/Update/Select even with Search function.
Well, now the most modern way is to have a RESTful API, that's even easier with Yii, you even don't need to care about all the columns, just 4 lines of code you can expose your database table as RESTful API with all GET/POST/PUT/DELETE support, even you change your database table columns, you don't need to change any PHP code.
For security, Yii have embedded authentication and RBAC support. For multi language, Yii have embedded i18n support, all with out-of-box. Just play with it, I bet you will love it.
