Code improvement. How to improve checks?

Question

PHP

There is a page where user data is displayed. There are 2 avatar pictures and a background, I check for the presence of a path in the database, if there is a path, then it shows a picture; if not, then the default picture, but for each picture you have to do the same checks, and it looks terrible. How can this be improved?

Answer 1

We write a method that returns true or false and checks for the presence of any image, depending on the passed key. We write a getter that returns a url, in which the condition depends on the execution of the first method. And it's all in the user object. Then just$user->avatar
