in Php how to remove emoji code?

问题

Users sometimes input some emoji in my BBS, but I am using MySQL version 5.0 which cannot store emoji code (as UTF).

I can not upgrade MySQL to 5.5 right now, so is there any safe way to filter the emoji code?

First, I don't know how to remove emoji code.

If you can't upgrade to mysql5.5, storing your text using the blob type will resolve your problem.
