I visualized a class about variable variable in PHP and I came up with the following question, which is the application of this variable format? if it’s not too much to ask, a simple and practical example. Grateful!

Hardly any. PHP usage a long time ago and I never needed to use it - and every time I saw someone using it was unnecessary, usually not to have the trouble of redoing it the way correct.

Thalles, I just wanted to let you know that the system penalizes users who create and delete multiple questions. I noticed that you created some questions that were not well received and that you promptly deleted them. Be careful with that. Some of them would probably be closed, or because they are broad, unclear or outside the scope of the site. If you still have any questions about the site, you can go to [help]; or when you have 20 reputation points, you are welcome to chat.
