Is the handle a concept exclusive to the windows operating system? This post was last edited by shopnc_02 from 2014-10-2812: 30: 54. why should I raise this question, this logic seems to be frequently used in PHP, so I want to understand it. Baidu once, it seems that the handle is a product in windows, so other systems, such as Linux & nbsp;, Uyun, and other operating systems, also have handles that belong to windows operating systems.

Why do you want to raise this question? it seems that this logic is often used in PHP, so I want to understand it. Baidu once seems that the handle is a product in windows, so does another system, such as Linux and UINX, also have this stuff? There is also the concept of hooks. it seems that the handle is also a hook, so what is the hook? PHP is messy.
Also, $ _ mysqli = new mysqli ('cocalhost', 'root', 'angfan ', 'cms'); in this sentence, why do we say $ _ mysqli is the handle?
I understand it as a variable.
------ Solution ----------------------
Let's just say:
Resources actually exist, such as you.
A variable is a carrier or a name. For example, your ID card will never be shopnc_02, but he represents you.
