添付ファイル付きのフォームをメールしようとしましたが、私のメールに$ headerを含めると送信に失敗します：mail("[email protected]", $subject, $message, $headers) そして、私は？：PHPヘッダが添付されているとPHPメールを送信できませんでした
：しかし、添付されて送信がテキストデータではなく、実際の添付画像PNG form.EverythingはW/O境界まで詰め込まれている画像は、私はこのウェブサイトからコードを試してみました

ただし、添付ファイルに名前がなく、ファイルタイプが –
$ headers。= "MIME-Version：1.0 \ r \ n"になっていません。 "Content-Type：multipart/mixed; \ r \ n"; –
まだ添付ファイルには名前はなく、拡張子はありませんので、どのプログラムでも開くことはできません –
