In my previous post, I’ve mentioned that it is up to the implementation to define whether the function will behave properly. Another issue that I can came out with is the readability of your code to average Gilbert. I have once written a function, which came back to bite my team. The function briefly return whether the user is activated or not, and return NULL when the user is not found.

Yes. It is been a long time.

This is a repost of a post in Tumblr over a years ago. Time flies and I found the solution.
