HomeBackend DevelopmentPHP TutorialString constant PHP reverse string function strrev function usage

Haha, it’s fun. I really want to make a function encyclopedia website, but because my energy is limited, I am busy enough just writing WEB development notes and updating one article a day, because my career is not just about writing. This blog, as well as many other websites, need to be maintained. I just write soft articles and publish original works every day. It is really tiring. Well, if I have the opportunity in the future, I will still build the Function Encyclopedia Network. I hope everyone will support it.
