The point about the mysql field is the delimiter

Insert INTO `users` ( ​​`UserName` , `PassWord`
Some people do not standardize the field names, which will cause conflicts. It has some escaping functions
You don’t have to use it. If there is a conflict, use it

The above has introduced the point about the mysql field as the delimiter, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
