PHPでMIMETYPEから拡張子を判定する用の配列

base64encodeされたデータから、MIMETYPEを取得して拡張子を判定したかった

Codeigniterに拡張子→MIMETYPEはあったけど
その逆はなかったので、配列のkeyから拡張子を判定できるような配列が欲しかった。

ユーザーのアップロードで使いそうなのはこれくらい。

$mimetypes = array();

// ZIP関係
$mimetypes["application/x-7z-compressed"]  => ".7z";
$mimetypes["application/x-zip-compressed"] => ".zip";
$mimetypes["application/x-gzip"]           => ".gz";

// 画像関係
$mimetypes["image/gif"]  => ".gif";
$mimetypes["image/jpeg"] => ".jpg";
$mimetypes["image/png"]  => ".png";

// Word
$mimetypes["application/msword"] => ".doc";
$mimetypes["application/vnd.openxmlformats-officedocument.wordprocessingml.document"] => ".docx";

// Excel
$mimetypes["application/vnd.ms-excel"] => ".xls";
$mimetypes["application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"] => ".xlsx";

// PowerPoint
$mimetypes["application/vnd.ms-powerpoint"] => ".ppt";
$mimetypes["application/vnd.openxmlformats-officedocument.presentationml.presentation"] => ".pptx";

// PDF
$mimetypes["application/pdf"] => ".pdf";

以下は一覧。
ただ、keyがユニークじゃないので適宜変更必要。
