Note Submitter: smilepet dot 26 at gmail dot com ---- I see this type of comment everywhere "this isn't the problem but it also wouldn't hurt to remove the Content-Transfer-Encoding header field. It doesn't exist in HTTP.". My question is if "Content-Transfer-Encoding" is really unnecessary, why does this is included in the above example from PHP Group? Because of this example usage, we could find the same kind of script being written again and again everywhere. Is there something wrong in this use?
