Hi Will you please tell me which is the Most of all Using Framework and also easy one to develop PHP Projects.
There is nothing like best framework. The best framework is which you feel comfortable with.
And one that is actively developed, has useful documentation, and community support.
A few past threads:

Of course it’s all in the eye of the beholder, but from looking at what’s happening online these days, the standout seems to be Laravel—which, according to its devotees, is the first PHP framework to seriously rival Rails.
There is no such thing called best framework, each has its own strengths and weaknesses, you have to judge it for yourself and sometimes play around with them for a while to decide which suits your need better. For me, I write my own framework since none of the frameworks actually work for the application I am working on, there are times when you will find yourself in such a situation too.
Those must be some awfully unique requirements! 
From a beginner viewpoint I like codeigniter. The others I have looked at appear to have steeper learning curves.

I have tried several frameworks but still prefer CodeIgniter because of the good documentation and helpful forum.
>>> one of the frameworks actually work for the application I am working on
CodeIgniter handles far more than just the basic PHP routines and does save time in “reinventing the wheel”. Their “core” classes can easily be either adjusted to suit particular requirements or even completely rewritten. Your own or other libraries and hooks are easily integrated. I am curious to know of your special requirements.
Thanks Force Flow.This is helpful for me.
