Which php framework you like the most in term of ease of use and speed? 1. Code Igniter 2. Cakephp 3. Zend 4. Symfony 5. Yii

i made a comparison , using single controller to print hello statement , speed goes to Codeigniter Ease Goes to Codeigniter and Yii So my Recommendation goes to Codeigniter

In terms of speed, it matters on the scale of your application is going to be.
If there is a big scale application then do use symfony2.xx(hard to understand the concepts and installation is lengthy).
While working on small scale project do use Codeigniter or Yii (quite fast and reliable).
Codeigniter or Yii are also used in big scale projects is used properly like HMVC patterns and ORM integrated.

CakePHP is the best.! you can even make big CRM, ERP like applications in very short period of time by using command line. I have done it and practically implemented it.

Once database has been finalized, it's very easy to implement, even it may take one hour to develop whole CRM / ERP Application using command line and then it may take one month to implement business logic, data validations, sanitization etc.

It may take one month for requirement analysis, one month in finalizing database and rest of one month in configuration so total3 months roughly required for any big application like CRM / ERP level. 

Zend Framework then codeigniter

YII for sure is the most perfect one for me

Codeigniter is powerful and have a very lite footprint you do not feel that you cancel your brain :)

I use CodeIgniter and zend in developing, if you want quick and easy to learn framework then codeIgniter will be the best.
if you want to build complex system (which security and integration with third pary is important) then Zend will be the best solution

I will recommend YII

I will recommend CodeIgniter.

I use zend framework

Yii Framework for sure.
