PHP Mail mit UTF-8 Headers und Umlaute wie ÖÄÜ+ß

Damit Empfänger Umlaute vernünftig lesen kann, muss man E-Mail mit Headers (MIME, Content-type, charset) schicken.

<?php

    $to_email = "max@gmail.com";

    $sender_email = "my@email.com";

    $mail_subject = "Mail subject comes here";

    

    $headers   = array();

    $headers[] = "MIME-Version: 1.0";

    $headers[] = "Content-type: text/plain; charset=utf-8";

    $headers[] = "From: My Name <$sender_email>";

    $headers[] = "Cc: copy@example.com ";

    $headers[] = "Bcc: hidden@example.com ";

    $headers[] = "Reply-To: {$sender_email}";

    $headers[] = "Subject: {$mail_subject}";

    $headers[] = "X-Mailer: PHP/" . phpversion();

    

    $headers_final = implode("\r\n", $headers);

    

    mail($to_email, $mail_subject, "Mail content comes here", $headers_final);
