In this question: my php script does not work, the answer was migrated away correctly to Stack Overflow.
Stack Overflow closed the question being unclear as I was adding my answer and that action migrated it back to SuperUser.
How can I post my answer now? To me it is clear as day what the question is and the answer is relatively simple too, but I have too little reputation on Stack Overflow to do anything. I did flag the question, but given that it was migrated back to SuperUser, I doubt they can do anything with the question now.
How does this work?
