Finding problems in the current code

Till now, we have written our blog post's endpoint-related code, and I left to do the same with the comment-related endpoints. If you haven't done that, then I insist that you do that first, or at least try to do so because without practice, it doesn't last for much time, so keep practicing at least when some code examples are provided or there are some tasks to do.

Anyway, as we have written code to implement RESTful web service endpoints in the last chapter, we are going to dig into that and identify what is missing and what types of improvements are required.

Structural and design flaws

Right now in our code, there are some flaws we can identify very clearly.

Missing query builder layer

Although we are using PDO, we still always to write a query need to carry out many low level things such as being aware of SQL injection (due to which we have to use the prepare statement, then bind values), to perform database-related operations. We should use some...
