The protagonist is a programmer, and everything revolves around Xiao Shuai Shuai as a guide to carry out this project.

Back to business:

After practicing all night, Xiao Shuaishuai returned to the company listlessly with dark circles under his eyes. He happened to meet Boss Yu and said excitedly: Boss Yu, the one you gave me yesterday PHP Simple HTML DOM Parser, I spent a whole night looking at it and finally figured it out. I will send you the code later to help you see if there are any problems?

Boss Yu looked at Xiao Shuaishuai with dark circles and said: You stayed up late, I will give you a day off today, have a good rest, you will be stronger when you are in good spirits, pay attention to rest next time, don't affect the next day work.

Xiao Shuaishuai also felt that it was not good to work like this, so he said to the boss: Thank you, boss Yu. I will pay attention to it next time. I will send you the code later and then go back to rest.

Boss Yu couldn’t say anything more, so he had to agree: Okay.
