PHP reverse string function strrev () Usage

I really want to create a function for Baike. I only write WEB Development notes because of my limited energy. I am busy updating an article a day, because, my career is not just about writing this blog, but there are many other websites that need maintenance. I write soft texts and make original posts every day. I am so tired. Well, I will have a chance in the future, I still want to implement the function Baike network, and hope everyone can support it.
