In the previous article, we said that you can currently apply for a trial account of SAE. Just applying for an account and creating an application is not enough. We need to enrich the content. A good VPS is for laymen in PHP, programming, and development. I can only follow what others have written. Therefore, these so-called tutorials are not my own original creation. I just practiced what others wrote and sorted them out again. I typed them out word by word.
