quality standard required

My project was submitted several times and was rejected by the quality requirements, but I don’t know what kind of request? I hope that the author or auditor who has passed the same problem can help solve the problem, is the PHP project, thank you!

Hasn’t anyone ever filed a complaint that the quality does not match? Can the official come out to answer it!
