I've seen this question: How can I prevent SQL injection in PHP?
It's a very popular one on StackOverflow, and I've noticed something, it's not community wiki.
According to What are "Community Wiki" posts?, a question should become CW ones it accumulated 30 answers,
that one has 37didn't notice 21 of those were deleted, so it doesn't count.
Also, the first, accepted answer, used to be CW, and is now no longer one. The answer was very heavily community-edited, and I don't think a single user should receive reputation for it.
Why aren't those posts community wiki?
