Hi @codingdefined thank you for reviewing this submission. While SteemSQL is not open source, it is used in open source projects which have been approved many times on Utopoian, such as SteemSQL wrapper (https://utopian.io/project/sihaelov/steemsql-wrapper/github/114453017/all).
This code that I have provided might look simple, but it is asked by many programmers on the steemit.chat steemSQL channel, as @arcange and @justyy will tell you, how many times people ask this question, how to connect to SteemSQL using PHP7. This code takes a long time to figure out without a reference point and it is a good resource for future open source PHP developers planning on using SteemSQL as the backend. If I provided a complex example here it will lose the purpose of this project, which is to help PHP programmers get started on SteemSQL.
Thank you for your consideration & Merry Christmas to you :)

p.s. If you google SteemSQL PHP7, this article is the most relevant in the search result.

Hi @magicmonk, I have talked about this with my supervisor and we still think it is too short as a dev contribution.
