Here is an RFC 4180-complient implementation in PHP. This can parse more than 1MiB of CSV text per second, so should be fast enough for most uses. It is fairly strict, in that it does not allow whitespace before the start of a quoted item, such as 1, "2" ,3 , in according to the standard, but it would be simple to make it laxer.
