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.
