As the question, I am engaged in a little mixed, who can be careful to talk about: 1, composer psr-0 and psr-4 In the difference; 2, psr-0 specifications and psr-4 specifications of the difference; 3. composer and php-fig. For example, I am a bit confused. Who can tell me carefully: 1. The difference between psr-

efficient cooperation Since the iphone watch has fewer interfaces, its main function is as a reminder that its pages do not appear as many interfaces as the phone. So it gives everyone a very efficient way to develop, when the front end of all the structure is made to enter the visual adjustment, you can spend one or two nights with him to work overtime for visual adjustment and fitness, if you are still a cute girl with high value of the matter will be more smooth, You can use your pixel eye

Very often when we create some view dynamically, we need to determine the layout of the other view by obtaining their width and height, but OnCreate () gets the width and height of the view to get 0.view.getwidth () and View.getheight () is the root cause of 0 because the control hasn't finished drawing yet, you have to wait for the system to finish drawing the view before you can get it.

PSR Specification PSR Specification Introduction: PSR is a shorthand for PHP standard recommendations, PHP specifications developed by the PHP FIG organization, is the practice of PHP development standards. The purpose of these specifications is to: through the framework of the author or the representative of the framework of the discussion, with the minimum limit, the development of a collaborative standard, each framework to follow a unified coding norms, to avoid the development of the style

very often when we create certain view dynamically, we need to determine the layout of the other view by getting their width and height, but the width and height of the view in OnCreate () get 0. The root cause of view.getwidth () and view.getheight () 0 is that the control has not finished drawing and you have to wait for the system to finish drawing the view before you can get it.

This question is the same as the two-point question. It only divides numbers into two heaps and uses the binary sorting method. However, it must be understood that it is not a condition to be found, there may be only duplicates. Here is the focus. As I continue my second journey, my time is very complex and the efficiency is not very good. After reading other people's code, it seems that all of them use hash, And the next stop is hash. 4 Values whose
