Which one is the best framework in php?

There is no best framework. It all depends on what you're trying to achieve, and if the workplace is willing to standardize on that specific framework

Here's some of the most popular Agile Frameworks:

- CakePHP

- Symfony

- Zend Framework

- FuelPHP

Here's some of the most popular AJAX Frameworks:

- jQuery

- Wijmo

- Kendo UI

- jQWidgets (which uses jQuery on the backend)

FuelPHP is good. Have MVC architecture. Template oriented. Have good ORM.  Still improving.

I prefer Laravel .... whereas; Symfony is also better

As you mentioned PHP framework . My personal experience is always go with laravel. Laravel have the great documentation fro learning and huge community where you can find your solution during your development. You can choose Laravel over Symfony because it's use some  components of Symfony.

My second choice is always Codeigniter It have very good user guide  and I used CI from last 3 years It give us all feature that we want in our project.

To me Yii is the best framework so far!

To my mind Laravel an YII.

Zend Framework is a good foundation for everything and can be used also as just a library of various functions.  It is also the closest thing to be  an "official" PHP framework so there are a lot of developers who know how to use it.  It is, however, not a framework you would use to prototype something very quickly.

The best Framework PHP is Laraval.
